Nexperia USA Inc. 74HC4002D/C4J

Overview

74HC4002D/C4J from NXP Semiconductors is a dual 2-input NOR gate IC in SOIC-14 package, operating at 2V–6V supply, with typical propagation delay of 10ns at 4.5V and output drive capability of ±5.2mA. It performs basic logic inversion and summation in digital control circuits for industrial timers and sensor interface modules.

For engineers reviewing the 74HC4002D/C4J datasheet, 74HC4002D/C4J pinout, 74HC4002D/C4J application, or 74HC4002D/C4J equivalent, key selection criteria include supply voltage range, propagation delay consistency across temperature, fan-out capability, and compatibility with 74HCT-level input thresholds in mixed-logic systems.

Technical Context

This device implements two independent CMOS NOR gates using silicon-gate technology, ensuring rail-to-rail output swing and high noise immunity. Each gate exhibits symmetrical rise/fall times (typ. 9ns) and supports direct interfacing with TTL and other 74HC-series logic without level-shifting.

It operates within −40°C to +125°C ambient range and meets JEDEC JESD78 Class II latch-up immunity. Input hysteresis is not present; inputs are standard CMOS with no Schmitt-trigger action.

FAQ

Is 74HC4002D/C4J pin-compatible with 74LS4002?

No. While both are dual 2-input NOR gates, 74LS4002 uses bipolar TTL technology with different DC characteristics: higher supply current (19mA typical), lower noise immunity, and incompatible input thresholds. Physical pinout matches, but direct substitution requires verification of fan-out, voltage margins, and timing budgets.

Can 74HC4002D/C4J operate reliably at 2.0V supply?

Yes. The device is fully specified down to 2.0V: propagation delay remains ≤35ns, output drive sustains ±2.6mA, and input thresholds scale proportionally. This enables use in energy-harvesting or coin-cell-powered logic monitoring circuits without voltage boosting.

What is the maximum clock frequency for toggle operation?

74HC4002D/C4J is not a clocked device and has no defined maximum toggle frequency. Its usable switching rate depends on external load capacitance and supply voltage; with 50pF load and 4.5V supply, maximum reliable toggle rate is ~35MHz based on propagation delay and transition time limits.

Does this part include input hysteresis or Schmitt-trigger inputs?

No. 74HC4002D/C4J features standard CMOS inputs without hysteresis. Input thresholds are fixed ratios of VCC (typically 0.5×VCC). For noisy signal conditioning, external RC filtering or dedicated Schmitt-trigger buffers like 74HC14 must be used.
