Nexperia USA Inc. 74LVC32APW,112

Overview

74LVC32APW,112 from Nexperia is a quad 2-input OR gate logic IC in TSSOP14 package, operating from 1.2 V to 3.6 V supply, with overvoltage-tolerant inputs up to 5.5 V and Schmitt-trigger inputs for noise immunity. It enables level translation between 3.3 V and 5 V systems and delivers propagation delay as low as 1.0 ns at 3.3 V in industrial-extended temperature range (−40 °C to +125 °C).

For engineers reviewing the 74LVC32APW,112 datasheet, 74LVC32APW,112 pinout, 74LVC32APW,112 application, or 74LVC32APW,112 equivalent, key selection criteria include input voltage tolerance, propagation delay across VCC range, output drive strength (±24 mA), thermal performance in TSSOP14, and JEDEC-compliant interface compatibility with TTL and mixed-voltage logic buses.

Technical Context

This device implements four independent OR logic functions with Schmitt-trigger inputs, enabling robust operation with slow-rising or noisy signals. Each gate accepts dual inputs referenced to GND and produces a single CMOS-compatible output referenced to VCC.

It supports wide VCC operation (1.2–3.6 V) while maintaining 5.5 V overvoltage tolerance on all inputs-critical for interfacing legacy 5 V peripherals with modern low-voltage controllers. The design complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36 across defined voltage bands.

FAQ

Can 74LVC32APW,112 safely interface a 5 V encoder output with a 1.8 V microcontroller GPIO?

Yes. Its inputs tolerate up to 5.5 V regardless of VCC, and its 1.2 V minimum supply allows direct connection to 1.8 V systems. Output VOH/VOL remain compatible with 1.8 V logic thresholds (VIH ≥ 1.08 V, VIL ≤ 0.12 V at VCC = 1.2 V), enabling true bidirectional voltage translation without external components.

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

Per datasheet test conditions, 74LVC32APW,112 maintains guaranteed tpd up to 50 pF load capacitance at VCC = 3.0–3.6 V with 500 Ω termination. Driving >50 pF increases propagation delay nonlinearly and may degrade edge rates; for >100 pF loads, consider buffering or reducing trace length and stubs.

Does the TSSOP14 package (SOT402-1) require special PCB layout considerations for thermal management?

Yes. While rated for 500 mW total power dissipation at Tamb ≤ 81 °C, the TSSOP14 derates at 7.3 mW/K above that temperature. To sustain full output drive at high ambient temperatures, provide ≥2 cm² of 2-oz copper pour connected to Pin 7 (GND) beneath the package, and avoid enclosing the device in sealed enclosures without airflow.

How does Schmitt-trigger input behavior affect timing analysis in synchronous designs?

Schmitt-trigger inputs introduce hysteresis (≥0.35 V at VCC = 2.3–2.7 V), which prevents chatter on slow or noisy edges but adds minor, non-deterministic delay variation (typically <0.5 ns). For synchronous timing closure, treat input transition as occurring at the midpoint voltage (VM = 0.5 × VCC) and verify setup/hold margins using worst-case tPLH/tPHL values from Table 7-not the hysteresis threshold.
