Nexperia USA Inc. 74VHC32PW,118

Overview

74VHC32PW,118 from Nexperia is a quad 2-input OR gate in TSSOP14 package, operating at 2.0–5.5 V supply with CMOS input levels, 7 ns typical propagation delay at 5 V/15 pF, and -40 °C to +125 °C temperature range-used for logic-level signal combining in industrial control I/O expansion and power management sequencing.

For engineers reviewing the 74VHC32PW,118 datasheet, 74VHC32PW,118 pinout, 74VHC32PW,118 application, or 74VHC32PW,118 equivalent, key selection criteria include input voltage compatibility (CMOS), propagation delay vs. load capacitance, thermal derating behavior in TSSOP14, and Schmitt-trigger input tolerance for noisy environments.

Technical Context

This device implements four independent OR logic functions using high-speed Si-gate CMOS technology, fully compliant with JEDEC 7-A and pin-compatible with LSTTL. It features balanced tPLH/tPHL propagation delays and operates across dual voltage domains: 2.0–5.5 V for 74VHC32 and 4.5–5.5 V for 74VHCT32 variants.

All inputs accept voltages up to 7.0 V regardless of VCC, enabling mixed-voltage interfacing. Static characteristics include VIH = 3.85 V (min) and VOL = 0.55 V (max) at 8 mA sink current and 125 °C, ensuring robust noise margins in harsh ambient conditions.

FAQ

Can 74VHC32PW,118 operate reliably at 2.0 V supply?

Yes. The device is fully specified down to 2.0 V supply, with guaranteed VIH ≥ 1.5 V and VOL ≤ 0.5 V at 4 mA load and 125 °C. Propagation delay increases to 10 ns max at 2.0 V/15 pF, but functionality remains intact across the full temperature range.

Does this part support mixed-voltage operation between inputs and VCC?

Yes. Inputs tolerate −0.5 V to +7.0 V independent of VCC, allowing direct connection to 5 V signals while powered from 3.3 V. No external clamping diodes or level shifters are needed, provided input current stays within ±20 mA limits.

What is the thermal derating behavior for TSSOP14 package at elevated ambient?

The TSSOP14 (SOT402-1) package derates total power dissipation linearly at 7.3 mW/K above 81 °C. At 125 °C ambient, maximum allowed Ptot drops to ~350 mW - sufficient for typical logic loading (<10 mW/gate) even at full temperature.

Are Schmitt-trigger inputs enabled on all four gates?

Yes. All eight inputs (1A–4B) feature Schmitt-trigger action with typical hysteresis of 0.3 V at VCC = 5 V. This ensures clean, bounce-free transitions for slow-rising signals such as mechanical switch inputs or RC-filtered sensor outputs.
