TLV2774ID Equivalent & Substitute Parts
Part Overview
The TLV2774ID is a CMOS rail-to-rail operational amplifier containing four independent circuits in a 14-SOIC surface mount package. Manufactured by Texas Instruments, this device is designated as Last Time Buy, indicating discontinued production with limited inventory availability. The TLV2774ID operates across a 2.5V to 5.5V supply range and is suitable for low-power analog signal processing applications requiring CMOS technology characteristics.
Substitute parts are necessary due to the Last Time Buy status of the TLV2774ID. Alternative devices with equivalent electrical and mechanical specifications ensure design continuity and long-term supply chain reliability.

Engineering Selection Recommendations
Tier 1: Recommended Direct Substitutes
TLV2774IDR (Texas Instruments) is the primary recommended substitute. This part maintains identical electrical specifications to the TLV2774ID with CMOS amplifier type, 10.5 V/µs slew rate, and 5.1 MHz gain bandwidth product. The only difference is packaging format (Tape & Reel versus Tube), which does not affect electrical performance. Product status is Active, ensuring long-term availability.
AD8604ARZ, AD8604ARZ-REEL, and AD8604ARZ-REEL7 (Analog Devices Inc.) are secondary CMOS substitutes. These devices exceed the TLV2774ID specifications with 8.4 MHz gain bandwidth product, superior input bias current (0.2 pA), and lower input offset voltage (80 µV). All variants maintain 50 mA output current per channel and operate across the required -40°C to 125°C temperature range. Product status is Active with high inventory availability. Packaging options include Tube and Cut Tape & Digi-Reel® formats.
Tier 2: Functional Equivalents
LMV824IDT and LMV824IYDT (STMicroelectronics) are general purpose amplifiers meeting the 14-SOIC package and rail-to-rail output requirements. Both parts operate across the full -40°C to 125°C temperature range with 2.5V to 5.5V supply compatibility. LMV824IYDT has significantly higher inventory (97,800 pcs) compared to LMV824IDT (20,755 pcs). Both carry AEC-Q100 automotive qualification and ROHS3 compliance. Trade-offs include lower slew rate (1.9 V/µs) and higher input offset voltage (3.5 mV).
LMV824DR2G (onsemi) is a general purpose alternative with Active product status. This part operates at -40°C to 85°C, which is narrower than the TLV2774ID range. Slew rate is significantly lower at 2 V/µs, and input bias current is substantially higher at 119 nA.
MCP604 variants (Microchip Technology) including MCP604-E/SL, MCP604-I/SL, and MCP604T-E/SL are CMOS amplifiers with lower performance specifications. Slew rate is 2.3 V/µs and gain bandwidth product is 2.8 MHz, both below TLV2774ID values. Output current per channel is limited to 22 mA. These parts are suitable only for applications with relaxed performance requirements.
Selection Criteria by Application:
For applications requiring performance matching or exceeding the TLV2774ID, select TLV2774IDR or AD8604 variants. For cost-optimized designs with relaxed bandwidth and slew rate requirements, LMV824 or MCP604 variants are acceptable. For automotive-qualified designs, LMV824IDT or LMV824IYDT provide AEC-Q100 certification.
Frequently Asked Questions (FAQ)
Q1: Can TLV2774IDR directly replace TLV2774ID without circuit modification?
A: Yes. TLV2774IDR is electrically identical to TLV2774ID. The only difference is packaging format (Tape & Reel versus Tube). Both devices have identical pin configuration, electrical specifications, and operating characteristics. No circuit modification is required.
Q2: What are the key differences between CMOS and General Purpose amplifier types in this comparison?
A: CMOS amplifiers (TLV2774ID, AD8604, MCP604) feature extremely low input bias current (typically 1-2 pA) and are optimized for high-impedance input applications. General Purpose amplifiers (LMV824) have higher input bias current (60-119 nA) but may offer other performance advantages. Selection depends on application requirements for input impedance and bias current characteristics.
Q3: Why do AD8604 variants show lower slew rate (6 V/µs) than TLV2774ID (10.5 V/µs) but higher gain bandwidth product (8.4 MHz versus 5.1 MHz)?
A: Slew rate and gain bandwidth product are independent performance metrics. AD8604 achieves higher bandwidth through different circuit topology while maintaining adequate slew rate for most applications. The 6 V/µs slew rate of AD8604 is sufficient for signal frequencies up to approximately 1 MHz with 10V peak-to-peak signals.
Q4: Are LMV824IDT and LMV824IYDT interchangeable?
A: Yes, LMV824IDT and LMV824IYDT are electrically identical. Both are STMicroelectronics general purpose amplifiers with identical specifications. The difference is inventory availability (LMV824IYDT has 97,800 pcs versus 20,755 pcs for LMV824IDT). Selection can be based on supply chain availability and lead time requirements.
Q5: What is the significance of AEC-Q100 qualification on LMV824 parts?
A: AEC-Q100 qualification indicates the device meets automotive industry reliability and quality standards. This certification is relevant only for automotive applications. For non-automotive applications, AEC-Q100 qualification provides no functional benefit but may increase component cost.
Q6: Can MCP604 variants be used in high-speed applications requiring 10 V/µs slew rate?
A: No. MCP604 variants have maximum slew rate of 2.3 V/µs, which is insufficient for applications requiring 10 V/µs performance. For high-speed applications, select TLV2774IDR or AD8604 variants. MCP604 is suitable only for low-frequency signal processing applications.
Q7: What is the impact of supply voltage range differences between substitutes?
A: TLV2774ID operates from 2.5V to 5.5V. AD8604 variants require minimum 2.7V supply. LMV824 and MCP604 variants support 2.5V to 5.5V or 2.7V to 6V ranges. For designs operating below 2.7V, only TLV2774IDR or LMV824 variants are suitable. For designs requiring supply voltages above 5.5V, MCP604 variants support up to 6V.
Q8: How does operating temperature range affect substitute selection?
A: TLV2774ID operates -40°C to 125°C. Most substitutes maintain this range except LMV824DR2G (-40°C to 85°C) and MCP604-I/SL (-40°C to 85°C). For applications requiring full -40°C to 125°C operation, avoid LMV824DR2G and MCP604-I/SL. Select TLV2774IDR, AD8604 variants, LMV824IDT, LMV824IYDT, MCP604-E/SL, or MCP604T-E/SL.
Q9: What packaging options are available for each substitute?
A: TLV2774IDR is available in Tape & Reel. AD8604ARZ is available in Tube. AD8604ARZ-REEL and AD8604ARZ-REEL7 are available in Cut Tape & Digi-Reel®. LMV824DR2G is Tape & Reel. LMV824IDT and LMV824IYDT are Cut Tape & Digi-Reel®. MCP604-E/SL and MCP604-I/SL are Tube. MCP604T-E/SL is Cut Tape & Digi-Reel®. Packaging selection depends on assembly process requirements and volume.
Q10: Are all substitutes ROHS3 compliant?
A: Yes. All listed substitutes carry ROHS3 compliance certification. All devices are also REACH Unaffected and classified as EAR99 for export control purposes.
