Nexperia USA Inc. 74AHC32PW,112

Overview

74AHC32PW,112 from Nexperia is a quad 2-input OR gate in TSSOP14 package, operating from 2.0 V to 5.5 V supply, featuring overvoltage-tolerant inputs up to 5.5 V, Schmitt-trigger inputs for noise immunity, and propagation delay as low as 2.8 ns (VCC = 5.0 V, CL = 15 pF). It serves as a level translator in mixed-voltage digital logic interfaces, such as interfacing 3.3 V microcontrollers with 5 V peripherals.

For engineers reviewing the 74AHC32PW,112 datasheet, 74AHC32PW,112 pinout, 74AHC32PW,112 application, or 74AHC32PW,112 equivalent, key selection criteria include input voltage compatibility across voltage domains, guaranteed propagation delay at 125 °C ambient, CMOS-level input thresholds, and thermal performance of the SOT402-1 package in space-constrained PCB layouts.

Technical Context

This device implements four independent OR logic functions (A + B = Y) with fully buffered outputs and rail-to-rail switching capability. Each input includes a Schmitt-trigger circuit to reject noise on slow or noisy signal edges, and all inputs tolerate voltages up to 5.5 V regardless of VCC - enabling safe bidirectional level translation between 2.0 V, 3.3 V, and 5.0 V logic domains.

The 74AHC32PW,112 operates across -40 °C to +125 °C with static VIH/VIL thresholds defined for 2.0 V, 3.0 V, and 5.5 V supplies, and dynamic timing characterized under load capacitances of 15 pF and 50 pF. Its power dissipation capacitance (CPD = 10 pF) supports accurate dynamic power estimation in high-frequency toggle scenarios.

FAQ

Can 74AHC32PW,112 operate reliably at 2.0 V supply?

Yes. The device is fully specified from 2.0 V to 5.5 V, with VIH = 1.5 V and VIL = 0.5 V at VCC = 2.0 V, and propagation delay ≤10.0 ns (max) under 125 °C conditions. Static and dynamic parameters are guaranteed across this full range per Table 5 and Table 7 of the datasheet.

Is the exposed pad on the TSSOP14 package electrically connected?

No. The thermal pad in SOT402-1 (TSSOP14) is not electrically connected to any internal node. Per section 5.1 of the datasheet, it may remain floating or be connected to GND if soldered - but no electrical requirement exists, and no internal bond wire attaches to it.

What is the maximum output current per pin for continuous DC operation?

The absolute maximum output current is ±25 mA per pin (Table 4), but recommended steady-state operation limits to ±8 mA (Table 6, VOH/VOL test conditions). Exceeding ±8 mA continuously risks exceeding junction temperature limits, especially at high ambient temperatures or high toggle rates.

Does 74AHC32PW,112 support hot insertion?

No. While inputs tolerate 5.5 V, the device lacks explicit hot-swap protection features such as power-on reset, I²t-rated current limiting, or back-drive immunity. Applying VCC after signal inputs may cause latch-up or excessive ICC due to internal parasitic paths - power sequencing must follow VCC-before-signals.
