TLV2455AIN Equivalent & Substitute Parts

Part Overview

The TLV2455AIN is a general-purpose operational amplifier manufactured by Texas Instruments, configured as a 4-circuit rail-to-rail amplifier in a 16-PDIP package. This device is designated as Last Time Buy, indicating discontinued production status. The TLV2455AIN operates across a supply voltage range of 2.7 V to 6 V with an operating temperature range of -40°C to 125°C, making it suitable for low-power analog signal processing applications.

Due to its Last Time Buy status, identifying equivalent substitute parts is necessary for design continuity and long-term component availability. The substitute part identified maintains electrical equivalence while offering alternative packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2455AIN is determined by electrical parameter equivalence across the following criteria:

Electrical Equivalence Parameters:

• Amplifier type classification (General Purpose)
• Number of integrated circuits (4 circuits)
• Output configuration (Rail-to-Rail)
• Slew rate (0.11 V/µs)
• Gain bandwidth product (220 kHz)
• Input bias current (500 pA)
• Input offset voltage (300 µV)
• Supply current per channel (23 µA x4 Channels)
• Output current per channel (10 mA)
• Supply voltage range (2.7 V to 6 V)
• Operating temperature range (-40°C to 125°C)

Mechanical Compatibility Parameters:

• Through-hole mounting type
• DIP package family
• 0.300" (7.62 mm) row spacing

The TLV2454AIN qualifies as an equivalent substitute based on identical electrical specifications. The primary distinction is the package configuration: the TLV2454AIN uses a 14-PDIP package versus the 16-PDIP of the TLV2455AIN. Both devices maintain the same functional circuit count and electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The TLV2454AIN serves as the direct electrical equivalent to the TLV2455AIN. Both devices are manufactured by Texas Instruments and maintain identical electrical performance specifications across all measured parameters including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and operating temperature range.

The TLV2454AIN holds Active product status, ensuring continued availability and manufacturing support, whereas the TLV2455AIN is designated Last Time Buy. This status difference makes the TLV2454AIN the preferred selection for new designs and long-term production requirements.

Both parts maintain ROHS3 compliance and are suitable for applications requiring low-power, general-purpose amplification in the 2.7 V to 6 V supply range. The package difference (14-PDIP versus 16-PDIP) reflects the same row spacing (0.300", 7.62 mm) and through-hole mounting compatibility, requiring only PCB layout adjustment to accommodate the reduced pin count.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between the TLV2455AIN and TLV2454AIN?

A: The devices are electrically identical. The TLV2455AIN uses a 16-PDIP package while the TLV2454AIN uses a 14-PDIP package. Both maintain 0.300" (7.62 mm) row spacing for through-hole mounting.

Q: Can the TLV2454AIN directly replace the TLV2455AIN on existing PCBs?

A: Direct socket replacement is not possible due to different pin counts (16 pins versus 14 pins). PCB redesign is required to accommodate the TLV2454AIN footprint.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both devices share identical specifications for slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, supply voltage range, and operating temperature range.

Q: Why is the TLV2455AIN marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production. The TLV2454AIN, with Active status, represents the current production alternative.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TLV2455AIN and TLV2454AIN are ROHS3 compliant and REACH unaffected.

Q: What supply voltage range do these amplifiers support?

A: Both devices operate across a supply voltage range of 2.7 V to 6 V, making them suitable for battery-powered and low-voltage applications.

Q: Are there any temperature range limitations?

A: Both parts operate across the identical temperature range of -40°C to 125°C, suitable for industrial and extended-temperature applications.
