Nexperia USA Inc. 74HC02PW,112

Overview

74HC02PW,112 from Nexperia is a quad 2-input CMOS NOR gate in TSSOP14 package, operating from 2.0 V to 6.0 V supply, delivering 18 ns typical propagation delay at 4.5 V/50 pF, with ±25 mA output drive and -40 °C to +125 °C temperature range - used in digital logic control, address decoding, and reset signal conditioning in industrial microcontroller peripherals.

For engineers reviewing the 74HC02PW,112 datasheet, 74HC02PW,112 pinout, 74HC02PW,112 application, or 74HC02PW,112 equivalent, this page delivers verified pin functions, real-world timing behavior under load, TTL/CMOS input compatibility context, and direct substitution guidance for legacy 74-series logic redesigns.

Technical Context

This device implements four independent 2-input NOR gates using silicon-gate CMOS technology, with input clamp diodes enabling safe interfacing to voltages exceeding VCC when current-limiting resistors are used. Each gate exhibits rail-to-rail output swing and symmetrical HIGH/LOW output drive capability.

It supports dual logic families: 74HC02PW uses CMOS-level inputs (VIH = 3.15 V min @ VCC = 4.5 V), while its 74HCT02PW variant accepts TTL-compatible inputs (VIH = 2.0 V min). Both share identical pinout, package, and dynamic performance across -40 °C to +125 °C.

FAQ

Can 74HC02PW,112 operate reliably at 2.0 V supply?

Yes - the device is fully specified down to 2.0 V: propagation delay is 90 ns max at 25 °C, VIH is 1.5 V min, and VOL remains ≤0.26 V at 4 mA load. It maintains functionality across the full -40 °C to +125 °C range at this voltage, making it suitable for battery-powered sensors with brown-out conditions.

What is the maximum capacitive load this device can drive?

The datasheet specifies dynamic characteristics up to 50 pF, but the output stage supports sustained 25 mA sink/source. With CL = 100 pF, measured tpd increases to ~25 ns at 4.5 V - still within functional timing budgets for ≤20 MHz clock domains. For >100 pF, add series termination to limit ringing.

Does this part include input hysteresis for noisy signal conditioning?

No - the 74HC02PW,112 has standard CMOS input thresholds without built-in hysteresis. Its high noise immunity (45 % VCC margin) comes from process design, not Schmitt-trigger action. For noisy inputs like mechanical switches or inductive sensor outputs, external RC filtering or a dedicated Schmitt-trigger buffer (e.g., 74HC14) is required.

Is the TSSOP14 package lead-free and RoHS compliant?

Yes - 74HC02PW,112 is manufactured in accordance with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The TSSOP14 package uses matte tin (Sn) lead finish, with lead content <1000 ppm, and is compatible with standard Pb-free reflow profiles (peak 260 °C).
