Engineering Selection Recommendations

Recommended Primary Substitute: TS464CDT

The TS464CDT from STMicroelectronics is the direct equivalent replacement for the obsolete TS464CD. This part maintains identical electrical specifications and mechanical packaging while offering active product status and ROHS3 compliance. Selection of TS464CDT is appropriate for applications requiring minimal design modification and direct pin-for-pin compatibility.

Recommended Secondary Substitutes: TL974ID / TL974IDR

The TL974 series from Texas Instruments provides functional equivalence with identical gain bandwidth product (12 MHz) and input bias current (200 nA) specifications. The TL974IDR variant in Cut Tape & Digi-Reel® packaging offers the highest inventory availability (20,138 units). These parts support extended operating temperature range (-40°C to 125°C) and ROHS3 compliance, suitable for applications requiring enhanced environmental performance.

Alternative Substitutes: OP462GSZ / OP462GSZ-REEL7

The OP462 series from Analog Devices Inc. exceeds the electrical performance of the TS464CD with higher slew rate (13V/µs vs. 4V/µs) and gain bandwidth product (15 MHz vs. 12 MHz). These parts are appropriate for applications requiring improved dynamic performance while maintaining the same 14-SOIC package footprint and rail-to-rail output configuration. ROHS3 compliance and extended temperature range (-40°C to 125°C) are provided.

Specialized Alternative: TLV2264AID / TLV2264AIDR

The TLV2264 series from Texas Instruments represents a CMOS amplifier alternative with significantly lower input bias current (1 pA vs. 200 nA). This part is suitable for applications requiring ultra-low input bias current characteristics. The reduced gain bandwidth product (710 kHz) and slew rate (0.55V/µs) limit applicability to lower-frequency signal processing circuits. Maximum supply voltage is restricted to 8V.

Performance-Enhanced Alternative: LM6584MA/NOPB / LM6584MAX/NOPB

The LM6584 series from Texas Instruments provides enhanced performance specifications including higher slew rate (15V/µs) and gain bandwidth product (24 MHz). These parts are suitable for video amplifier and high-speed signal processing applications. The LM6584MAX/NOPB variant in Tape & Reel packaging offers the highest inventory availability (2,600 units) among this product line.

Frequently Asked Questions (FAQ)

Q: Can TS464CDT be used as a direct replacement for TS464CD?

A: Yes. The TS464CDT maintains identical electrical specifications, pin configuration, and 14-SOIC package dimensions. The primary differences are active product status and ROHS3 compliance. No circuit modifications are required for substitution.

Q: What are the key differences between TS464CD and OP462GSZ?

A: Both devices are 4-circuit rail-to-rail amplifiers in 14-SOIC packages. The OP462GSZ provides superior performance with slew rate of 13V/µs (vs. 4V/µs) and gain bandwidth product of 15 MHz (vs. 12 MHz). Input offset voltage is significantly lower at 25 µV (vs. 1 mV). Supply current is reduced to 550µA per channel (vs. 2mA). Operating temperature range is extended to -40°C to 125°C. These enhancements make OP462GSZ suitable for higher-frequency applications.

Q: Is TLV2264AID compatible with TS464CD in all applications?

A: TLV2264AID shares the same 14-SOIC package and rail-to-rail output configuration. However, significant performance differences exist. The TLV2264AID has substantially lower gain bandwidth product (710 kHz vs. 12 MHz) and slew rate (0.55V/µs vs. 4V/µs), limiting it to low-frequency applications. Maximum supply voltage is 8V (vs. 10V). Substitution is appropriate only for low-speed signal conditioning circuits where the ultra-low input bias current (1 pA) is advantageous.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: Tube (OP462GSZ, TL974ID, TLV2264AID), Cut Tape & Digi-Reel® (TS464CDT, TL974IDR), and Tape & Reel (OP462GSZ-REEL7, LM6584MAX/NOPB, TLV2264AIDR). Selection depends on production volume and assembly process requirements. All variants maintain identical 14-SOIC (0.154", 3.90mm Width) package dimensions.

Q: Are all substitute parts RoHS compliant?

A: The original TS464CD is RoHS non-compliant. All recommended substitute parts (TS464CDT, OP462 series, TL974 series, LM6584 series, and TLV2264 series) are ROHS3 compliant. This compliance status is mandatory for applications subject to RoHS regulations.

Q: Which substitute provides the best performance for high-speed applications?

A: The LM6584 series provides the highest slew rate (15V/µs) and gain bandwidth product (24 MHz) among all substitutes. This makes LM6584MA/NOPB and LM6584MAX/NOPB optimal for video amplifier and high-speed signal processing applications. The LM6584MAX/NOPB variant in Tape & Reel packaging is recommended for high-volume production.

Q: What is the operating temperature range difference between TS464CD and its substitutes?

A: The TS464CD operates from -20°C to 70°C. Most active substitutes (OP462, TL974, LM6584, TLV2264 series) extend this range to -40°C to 125°C, providing enhanced environmental performance for industrial and automotive applications. This extended range is a standard feature of modern general-purpose amplifier designs.

Q: Can TS464CD be substituted with LM6584 in existing designs?

A: LM6584 is functionally compatible within the same 14-SOIC package. However, design verification is required due to performance differences. The LM6584 provides higher slew rate (15V/µs vs. 4V/µs) and gain bandwidth product (24 MHz vs. 12 MHz), which may affect circuit behavior in frequency-dependent applications. Supply current is lower (780 µA vs. 2mA per channel), reducing power consumption. Substitution is appropriate for applications where enhanced performance is beneficial or neutral.

Q: What inventory status should influence substitute selection?

A: Current inventory levels are: OP462GSZ (18,572 units), TL974IDR (20,138 units), TS464CDT (1,248 units), LM6584MAX/NOPB (2,600 units), OP462GSZ-REEL7 (5,200 units), and TLV2264AIDR (1,890 units). For high-volume production, TL974IDR and OP462GSZ offer the highest availability. For immediate requirements, OP462GSZ provides the largest stock position.
