Nexperia USA Inc. 74AHC32PW,118

Overview

74AHC32PW,118 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-translating logic buffer in mixed-voltage digital interfaces such as industrial I/O expansion and microcontroller peripheral gating.

For engineers reviewing the 74AHC32PW,118 datasheet, 74AHC32PW,118 pinout, 74AHC32PW,118 application, or 74AHC32PW,118 equivalent, key selection criteria include input voltage tolerance across supply domains, guaranteed operation at -40 °C to +125 °C, CMOS-level input compatibility, and TSSOP14 thermal performance under 8 mA output drive.

Technical Context

This device implements four independent OR logic functions with fully buffered outputs and rail-to-rail input voltage tolerance beyond VCC. Each gate features Schmitt-trigger action on both inputs, enabling robust operation with slow or noisy signals without external hysteresis components.

The 74AHC32PW,118 uses standard CMOS logic thresholds (VIH ≥ 3.85 V at VCC = 5.5 V; VIL ≤ 1.65 V), supports dynamic switching up to 100 MHz (at VCC = 5.0 V, CL = 15 pF), and maintains sub-0.55 V VOL at 8 mA sink current across its full temperature range.

FAQ

Can 74AHC32PW,118 operate with a 2.0 V supply and still drive a 5 V-tolerant input?

Yes - the 74AHC32PW,118 guarantees VOH ≥ 1.5 V at VCC = 2.0 V (IO = –50 µA), which meets minimum VIH requirements for many 3.3 V and 5 V CMOS inputs. Its overvoltage-tolerant inputs allow direct connection to 5 V nodes, but output swing is limited to VCC; level translation requires external circuitry for full 2.0 V → 5 V conversion.

Is the exposed pad on the TSSOP14 package electrically connected?

No - the thermal pad on SOT402-1 (TSSOP14) is not electrically connected to any internal node. Per Nexperia documentation, it may remain floating or be tied to GND for thermal improvement, but soldering it imposes no electrical requirement and introduces no risk of shorting.

What is the maximum capacitive load this device can drive while maintaining specified tpd?

The datasheet specifies propagation delay up to 50 pF load capacitance (CL = 50 pF) with tpd ≤ 7.5 ns at VCC = 5.0 V. Driving > 50 pF increases delay nonlinearly and may exceed recommended output current limits; for > 100 pF loads, consider buffering or reducing trace length to maintain timing integrity.

Does 74AHC32PW,118 support hot insertion or live backplane connection?

No - while inputs tolerate 5.5 V statically, the device lacks explicit hot-swap or Ioff protection. Applying VCC after inputs are driven risks contention current flow through input clamps. For live insertion, use dedicated hot-swap controllers or add series resistors and TVS diodes per input.
