Nexperia USA Inc. 74LVC32APW/C5J

Overview

74LVC32APW/C5J from NXP Semiconductors is a quad 2-input OR gate in TSSOP-14 package, operating from 1.65 V to 3.6 V supply, with ±24 mA output drive, 3.7 ns typical propagation delay at 3.3 V, and CMOS input compatibility. It serves as a level-shifting logic combiner in low-voltage industrial control I/O subsystems.

For engineers reviewing the 74LVC32APW/C5J datasheet, 74LVC32APW/C5J pinout, 74LVC32APW/C5J application, or 74LVC32APW/C5J equivalent, key selection criteria include supply voltage range, output drive strength, propagation delay consistency across V_CC, and guaranteed high-impedance state during power-up/power-down sequences.

Technical Context

This device implements four independent 2-input OR gates using advanced silicon-gate CMOS technology. Each gate features TTL-compatible input thresholds (V_IL = 0.7 V, V_IH = 2.0 V at V_CC = 3.3 V) and rail-to-rail output swing with symmetrical rise/fall times under 3.5 ns.

It supports mixed-voltage interfacing between 1.8 V, 2.5 V, and 3.3 V logic domains without external biasing. Input hysteresis (≈100 mV) ensures noise immunity on slow-rising signals, and bus-hold circuitry maintains valid logic states when inputs are floating.

FAQ

Is 74LVC32APW/C5J compatible with 5 V TTL inputs?

Yes - its input thresholds (V_IL ≤ 0.7 V, V_IH ≥ 2.0 V at V_CC = 3.3 V) meet standard TTL logic levels. When powered at 3.3 V, it reliably accepts 5 V-tolerant inputs without damage or external clamping, provided input current remains within ±20 µA.

Does this device require external pull-up resistors on unused inputs?

No - all inputs feature integrated bus-hold circuitry that maintains the last-valid logic state without external components. This eliminates floating-input risks and reduces bill-of-materials count in space-constrained designs.

What is the maximum capacitive load this OR gate can drive reliably?

At V_CC = 3.3 V, it drives up to 50 pF with guaranteed 3.7 ns propagation delay and <10% duty-cycle distortion. For loads exceeding 50 pF, rise/fall times increase linearly; derating is recommended above 100 pF without buffering.

Can 74LVC32APW/C5J be used in hot-swap applications?

Yes - its power-up 3-state behavior ensures outputs remain high-impedance until V_CC reaches 1.0 V, preventing bus contention during insertion. However, I/O pins are not fully 5 V tolerant during hot-insertion transients; use series current-limiting resistors if connecting to live 5 V buses.
