TLC2252AIPW Equivalent & Substitute Parts

Part Overview

The TLC2252AIPW is a general purpose operational amplifier featuring dual circuits in a rail-to-rail configuration, manufactured by Texas Instruments in the LinCMOS™ series. This device is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and production continuity. The TLC2252AIPW operates across a wide supply voltage range of 4.4 V to 16 V and is housed in an 8-TSSOP surface mount package. Substitute parts must maintain functional equivalence in amplifier topology, electrical performance, and physical packaging to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLC2252AIPW are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Electrical Equivalence Parameters:

• Dual-circuit configuration (2 circuits per package)
• Rail-to-rail output capability
• Slew rate of 0.12 V/µs
• Gain bandwidth product within 200–210 kHz range
• Input bias current of 1 pA
• Supply voltage span compatibility (minimum 4.4 V, maximum 16 V)
• Operating temperature range of -40°C to 125°C

Mechanical Equivalence Parameters:

• 8-pin surface mount package (8-TSSOP or 8-MiniSO)
• RoHS3 compliance
• Moisture sensitivity level 1

The TLC2252AIPWR represents a direct manufacturer-recommended substitute with identical electrical specifications and packaging. The TSX632IST and TSX632IYST (STMicroelectronics) provide functional substitution with minor parameter variations that remain within acceptable operational tolerances for general purpose amplifier applications.

Parameter Comparison

Engineering Selection Recommendations

TLC2252AIPWR (Texas Instruments): This part is the manufacturer-recommended substitute for the obsolete TLC2252AIPW. It maintains identical electrical specifications, supply voltage range, and package configuration. The TLC2252AIPWR is active in production status and carries ROHS3 compliance. Selection of this part ensures direct functional equivalence with no design modifications required.

TSX632IST (STMicroelectronics): This substitute provides functional compatibility with the following considerations: the TSX632IST operates at a lower minimum supply voltage (3.3 V versus 4.4 V), offers lower supply current consumption (45 µA versus 80 µA), and delivers higher output current per channel (92 mA versus 50 mA). The input offset voltage is higher at 1.6 mV compared to 200 µV. The gain bandwidth product is 200 kHz versus 210 kHz. The TSX632IST is active in production and ROHS3 compliant. This part is suitable for applications where lower power consumption and higher output drive capability are beneficial.

TSX632IYST (STMicroelectronics): This substitute is functionally equivalent to the TSX632IST with the addition of automotive-grade qualification (AEC-Q100). Electrical and performance parameters are identical to the TSX632IST. Selection of this part is appropriate for automotive applications requiring AEC-Q100 certification.

Frequently Asked Questions (FAQ)

Q: Can the TLC2252AIPWR be used as a direct replacement for the TLC2252AIPW?

A: Yes. The TLC2252AIPWR is the manufacturer-recommended substitute with identical electrical specifications, supply voltage range (4.4 V to 16 V), slew rate (0.12 V/µs), gain bandwidth product (210 kHz), and 8-TSSOP package configuration. No circuit modifications are required.

Q: What are the key differences between the TLC2252AIPW and the TSX632IST?

A: The TSX632IST differs in the following parameters: minimum supply voltage is 3.3 V (versus 4.4 V), supply current is 45 µA (versus 80 µA), output current per channel is 92 mA (versus 50 mA), input offset voltage is 1.6 mV (versus 200 µV), and gain bandwidth product is 200 kHz (versus 210 kHz). Both maintain 0.12 V/µs slew rate and rail-to-rail output. The TSX632IST package is 8-MiniSO rather than 8-TSSOP.

Q: Is the TSX632IYST suitable for automotive applications?

A: Yes. The TSX632IYST carries AEC-Q100 automotive qualification and is appropriate for automotive-grade designs. Electrical specifications are identical to the TSX632IST.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The TLC2252AIPWR, TSX632IST, and TSX632IYST are all ROHS3 compliant with moisture sensitivity level 1 (unlimited).

Q: What is the package difference between TLC2252AIPWR and TSX632IST?

A: The TLC2252AIPWR uses an 8-TSSOP package (0.173", 4.40mm width). The TSX632IST uses an 8-MiniSO package (0.118", 3.00mm width). Both are surface mount packages with 8 pins, but the physical dimensions differ. PCB layout modifications may be required when switching between these packages.

Q: Which substitute part offers the lowest power consumption?

A: The TSX632IST and TSX632IYST both offer lower supply current at 45 µA compared to the TLC2252AIPW at 80 µA, representing a 44% reduction in supply current consumption.

Q: Can the TSX632IST operate at the same minimum supply voltage as the TLC2252AIPW?

A: No. The TSX632IST has a minimum supply voltage of 3.3 V, while the TLC2252AIPW requires a minimum of 4.4 V. The TSX632IST can operate at lower supply voltages, providing greater design flexibility in low-voltage applications.
