Nexperia USA Inc. 74HC4002PW-Q100,11

Overview

74HC4002PW-Q100 from Nexperia is a dual 4-input NOR gate IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 2.0 V to 6.0 V, featuring CMOS low power dissipation, high noise immunity, and input clamp diodes enabling interface to voltages exceeding VCC in engine control and body electronics modules.

For engineers reviewing the 74HC4002PW-Q100 datasheet, 74HC4002PW-Q100 pinout, 74HC4002PW-Q100 application, or 74HC4002PW-Q100 equivalent, key selection criteria include automotive temperature compliance, dual independent 4-input logic function, TSSOP14 package footprint, and verified static/dynamic timing across 2.0–6.0 V supply rails.

Technical Context

This device implements two independent CMOS NOR gates, each accepting four inputs (1A–1D and 2A–2D) and producing complementary active-low outputs (1Y and 2Y), with input clamp diodes allowing safe interfacing to signals above VCC when used with current-limiting resistors. Logic behavior follows standard NOR truth table: output HIGH only when all four inputs are LOW.

It operates within JEDEC-compliant voltage standards JESD8C (2.7–3.6 V) and JESD7A (2.0–6.0 V), supports dynamic switching up to 150 ns propagation delay at 2.0 V, and maintains VIH/VIL thresholds scaling linearly with VCC - e.g., VIH = 0.7×VCC min at 25 °C per Table 6.

FAQ

Is 74HC4002PW-Q100 pin-compatible with non-automotive 74HC4002 variants?

Yes - the pinout matches standard 74HC4002 devices in TSSOP14 packages, including 74HC4002PW. However, the Q100 suffix denotes AEC-Q100 qualification, tighter parametric screening, and automotive-grade traceability; electrical specs are identical, but reliability testing exceeds commercial-grade parts.

Can unused inputs be left floating?

No - all unused inputs must be tied to VCC or GND. Floating CMOS inputs cause increased supply current, unpredictable logic states, and potential oscillation due to noise coupling; datasheet Table 2 explicitly defines 1A–1D and 2A–2D as data inputs requiring defined DC bias.

What is the maximum capacitive load this device can drive reliably?

Dynamic characteristics in Table 7 are specified with CL = 50 pF. While not an absolute limit, sustained loading beyond 75 pF may increase propagation delay and transition time beyond guaranteed specs; for >50 pF, verify timing margins using CPD = 16 pF and actual signal frequency per Equation in Section 10.

Does the 'n.c.' marking on pins 6 and 8 mean they are internally unused?

Yes - pins 6 and 8 are designated 'not connected' in Table 2 and Fig. 6. They have no internal bond wire or silicon connection; leaving them unconnected is mandatory. Routing traces or applying solder to these pins risks mechanical stress or unintended parasitic coupling in high-density layouts.
