Nexperia USA Inc. 74HC4002PW,118

Overview

74HC4002PW,118 from Nexperia is a dual 4-input CMOS NOR gate in TSSOP14 package, operating from 2.0 V to 6.0 V supply, delivering propagation delays as low as 9 ns at VCC = 6.0 V and CL = 50 pF, with guaranteed operation from –40 °C to +125 °C. It integrates input clamp diodes for overvoltage-tolerant interfacing and meets JESD7A and JESD8C standards.

For engineers reviewing the 74HC4002PW,118 datasheet, 74HC4002PW,118 pinout, 74HC4002PW,118 application, or 74HC4002PW,118 equivalent, key selection criteria include supply voltage range (2.0–6.0 V), dual-gate logic density, industrial temperature rating (–40 °C to +125 °C), output drive capability (±4.0 mA at VCC = 4.5 V), and TSSOP14 footprint compatibility with high-density PCB layouts.

Technical Context

This device implements two independent 4-input NOR functions using standard CMOS silicon technology, with inputs tolerant to voltages exceeding VCC via integrated clamp diodes. Each gate exhibits symmetrical propagation delay (tpd = tPHL = tPLH) and transition time (tt = tTHL = tTLH), supporting precise timing in combinational logic networks.

Logic behavior follows strict Boolean NOR truth table: output is HIGH only when all four inputs are LOW; any HIGH input forces output LOW. Static characteristics include VIH ≥ 3.15 V and VOL ≤ 0.26 V at VCC = 4.5 V and IO = 4.0 mA, ensuring robust noise margins across full temperature range.

FAQ

Is the 74HC4002PW,118 pin-compatible with older 74HC4002 variants in SO14 or DIP packages?

Yes - the 74HC4002PW,118 shares identical pin numbering and logic function with all 74HC4002 variants, including SO14 (74HC4002D) and DIP-14 (discontinued 74HC4002N). Pin 1 (1Y), pins 2–5 (1A–1D), pin 7 (GND), pins 9–12 (2A–2D), pin 13 (2Y), and pin 14 (VCC) map identically. Only physical package dimensions differ.

Can unused inputs be left floating, or must they be terminated?

Unused inputs must never be left floating. Each unconnected input (e.g., 1A–1D or 2A–2D) must be tied to VCC or GND via a pull-up or pull-down resistor (typically 10 kΩ) to prevent metastability, increased power consumption, and potential oscillation due to noise coupling into high-impedance CMOS gates.

What is the maximum capacitive load this device can drive reliably at 6.0 V supply?

At VCC = 6.0 V, the 74HC4002PW,118 maintains specified timing (tpd ≤ 17 ns, tt ≤ 13 ns) driving up to 50 pF load capacitance. For loads exceeding 50 pF, propagation delay increases linearly; driving >100 pF requires buffer staging or reduced clock frequency to maintain setup/hold timing margins.

Does this device support mixed-voltage interfacing between 3.3 V and 5 V domains?

Yes - with proper design. Inputs tolerate voltages up to VCC + 0.5 V, so a 74HC4002PW,118 powered at 3.3 V accepts 5 V inputs when current-limited (e.g., 10 kΩ series resistor). Outputs swing rail-to-rail, enabling direct 3.3 V logic feeding into 5 V-tolerant receivers, but not vice versa without level translation.
