Nexperia USA Inc. 74HC4002PW/C5J

Overview

74HC4002PW/C5J from Nexperia is a dual 4-input CMOS NOR gate in TSSOP14 package, operating from 2.0 V to 6.0 V supply, with propagation delay as low as 9 ns at VCC = 6.0 V and CL = 50 pF, input clamping diodes for overvoltage-tolerant interfacing, and guaranteed operation from −40 °C to +125 °C - used in digital logic control, bus arbitration, and reset signal conditioning in industrial PLCs and sensor interface modules.

For engineers reviewing the 74HC4002PW/C5J datasheet, 74HC4002PW/C5J pinout, 74HC4002PW/C5J application, or 74HC4002PW/C5J equivalent, key selection criteria include supply voltage range compatibility (2.0–6.0 V), output drive strength (±4.0 mA at VCC = 4.5 V), thermal rating (−40 °C to +125 °C), input clamp diode support for >VCC signaling, and TSSOP14 footprint constraints in space-constrained PCB layouts.

Technical Context

This device implements two independent 4-input NOR gates using high-speed silicon-gate CMOS technology. Each gate exhibits rail-to-rail output swing, defined static thresholds (VIH = 3.15 V min at VCC = 4.5 V; VIL = 1.35 V max), and symmetrical propagation delays (tpd = tPHL = tPLH) across both inputs and outputs.

Input clamping diodes allow safe connection to signals exceeding VCC when used with current-limiting resistors. The logic function follows strict Boolean NOR behavior: output is HIGH only when all four inputs are LOW; otherwise, output is LOW - enabling active-low enable, priority encoding, and combinational safety interlock functions.

FAQ

What is the maximum clock frequency supported by the 74HC4002PW/C5J?

The 74HC4002PW/C5J is a combinational logic device with no internal clock - its usable toggle rate depends on propagation delay and load capacitance. At VCC = 6.0 V and CL = 50 pF, typical tpd = 9 ns, supporting reliable operation up to ~55 MHz in feedback-free configurations. For synchronous systems, maximum input transition rates should stay below 1/(2 × tpd) ≈ 55 MHz to avoid race conditions.

Can the 74HC4002PW/C5J drive LED indicators directly?

No - the 74HC4002PW/C5J is not designed for direct LED driving. Its output current capability is ±4.0 mA at VCC = 4.5 V, insufficient for typical indicator LEDs requiring 5–20 mA. Use an external NPN transistor or dedicated LED driver IC. However, it can safely interface to LED driver inputs (e.g., TLC5916) via series resistor due to its input clamp diodes and CMOS-compatible voltage levels.

Are pins 6 and 8 truly unconnected, or do they serve a mechanical purpose?

Pins 6 and 8 are confirmed no-connect (n.c.) with no internal bond wire or circuit connection - they exist solely for mechanical symmetry and package mold alignment in the TSSOP14 (SOT402-1) footprint. Neither pin may be tied to VCC, GND, or any signal; doing so risks internal shorting or undefined behavior. Leave them floating per Nexperia's pin description Table 2.

Does the 74HC4002PW/C5J support mixed-voltage operation between inputs and VCC?

Yes - input clamp diodes allow individual inputs to tolerate voltages up to VCC + 0.5 V or down to −0.5 V relative to GND, provided input current is limited to ±20 mA. This enables safe interfacing with 5 V logic driving a 3.3 V powered 74HC4002PW/C5J, using a 1 kΩ series resistor per input to limit current to <1.7 mA at 5 V - verified per Section 7 limiting values and Figure 5 pin configuration.
