Nexperia USA Inc. 74HC32PW-Q100,118

Overview

74HC32PW-Q100 from Nexperia is an automotive-grade quad 2-input OR gate in TSSOP14 package, operating from 2.0 V to 6.0 V supply, qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C), with CMOS-level inputs, 18 ns typical propagation delay at 4.5 V, and symmetrical output drive for logic-level translation in body control modules.

For engineers reviewing the 74HC32PW-Q100 datasheet, 74HC32PW-Q100 pinout, 74HC32PW-Q100 application, or 74HC32PW-Q100 equivalent, this device supports high-noise-immunity digital combining in automotive powertrain interface circuits, battery management signal arbitration, and fault-status aggregation where TTL-compatible timing margins and latch-up robustness (>100 mA) are required.

Technical Context

This device implements four independent OR logic functions using standard CMOS process technology, with input clamp diodes enabling safe interfacing to voltages exceeding VCC via external current-limiting resistors. Each gate exhibits balanced tPHL/tPLH propagation delays and matched rise/fall transition times (tt ≤ 22 ns at 4.5 V).

It operates across two logic families: 74HC32PW-Q100 accepts CMOS-level inputs (VIH ≥ 3.15 V at VCC = 4.5 V), while its 74HCT32PW-Q100 variant supports TTL-level inputs (VIH ≥ 2.0 V). Both share identical pinout, package, and AEC-Q100 qualification.

FAQ

What is the maximum allowable supply voltage for continuous operation?

The absolute maximum supply voltage is +7.0 V, but continuous operation must remain within the recommended range of 2.0 V to 6.0 V. Exceeding 6.0 V risks accelerated parametric drift and violates JEDEC JESD7A compliance - sustained operation above 6.0 V voids AEC-Q100 qualification validity.

Can 74HC32PW-Q100 interface directly with 3.3 V microcontroller GPIOs?

Yes: at VCC = 4.5 V, VIH(min) = 3.15 V and VIL(max) = 1.35 V, providing 0.15 V noise margin above typical 3.3 V MCU VOH(2.9 V) and 1.95 V margin below VOL(0.4 V), satisfying both DC noise immunity and switching threshold stability requirements.

Is the exposed pad on the TSSOP14 package electrically connected?

No - the thermal pad in SOT402-1 is not electrically tied to any internal node. Per Nexperia documentation, it may be left floating or connected to GND for thermal improvement, but must never be tied to VCC or other potentials to avoid unintended current paths or ESD discharge anomalies.

How does input clamping affect external resistor selection for overvoltage protection?

Clamp diodes conduct when input voltage exceeds VCC + 0.5 V or falls below GND − 0.5 V. To limit IIK to ±20 mA max, series resistors must be ≥ |Vin − VCC| / 20 mA (e.g., 1 kΩ for 25 V input at 5 V VCC), ensuring diode conduction remains within safe current limits without thermal runaway.
