Nexperia USA Inc. 74AHC32PW-Q100J

Overview

74AHC32PW-Q100 from Nexperia is an automotive-qualified quad 2-input OR gate in TSSOP14 package, operating from 2.0 V to 5.5 V supply, with CMOS-level inputs, overvoltage-tolerant inputs up to 5.5 V, and guaranteed operation from –40 °C to +125 °C. It serves as a logic-level translator in mixed-voltage automotive subsystems such as body control modules and powertrain interface circuits.

For engineers reviewing the 74AHC32PW-Q100 datasheet, 74AHC32PW-Q100 pinout, 74AHC32PW-Q100 application, or 74AHC32PW-Q100 equivalent, key selection criteria include input voltage compatibility (CMOS), propagation delay (≤7.0 ns at 5 V/50 pF), AEC-Q100 Grade 1 qualification, overvoltage tolerance, and TSSOP14 thermal performance for space-constrained PCB layouts.

Technical Context

This device implements four independent OR logic functions with Schmitt-trigger inputs for enhanced noise immunity and balanced propagation delays across all channels. Its overvoltage-tolerant inputs enable direct interfacing between 3.3 V and 5 V domains without level-shifting circuitry.

The 74AHC32PW-Q100 uses standard CMOS logic thresholds (VIH = 3.85 V min at VCC = 5.5 V; VIL = 1.65 V max), delivers VOL ≤ 0.55 V at 8 mA sink current, and maintains ICC ≤ 40 μA at VCC = 5.5 V - supporting low-power always-on automotive functions.

FAQ

Is the 74AHC32PW-Q100 pin-compatible with the 74AHCT32PW-Q100?

Yes - both devices share identical TSSOP14 pinout (SOT402-1), same terminal numbering, and functionally equivalent OR gate architecture. The only functional difference lies in input voltage thresholds: 74AHC32PW-Q100 uses CMOS-compatible VIH/VIL, while 74AHCT32PW-Q100 uses TTL-compatible thresholds. No PCB redesign is needed for substitution.

Can the 74AHC32PW-Q100 safely interface a 5 V sensor output with a 3.3 V microcontroller?

Yes - its overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC level. When powered at 3.3 V, it correctly interprets 5 V sensor outputs as HIGH while maintaining valid CMOS output levels (VOH ≥ 3.0 V, VOL ≤ 0.44 V) compatible with 3.3 V MCU inputs.

What is the maximum capacitive load this device can drive reliably?

The 74AHC32PW-Q100 is characterized up to 50 pF load capacitance in dynamic testing, with typical propagation delay of 7.0 ns at VCC = 5 V. Driving >50 pF may increase delay nonlinearly and risk output ringing; for heavier loads, add series termination or buffer stages per Nexperia Application Note AN10862.

Does the exposed pad on the TSSOP14 package require grounding?

No - the exposed pad in SOT402-1 is thermally conductive but electrically isolated. Nexperia specifies no electrical or mechanical requirement to solder it. If soldered, the land must remain floating or be connected to GND; connecting to any other net risks latch-up or parametric shift.
