Nexperia USA Inc. 74AHCT02PW-Q100J

Overview

74AHCT02PW-Q100 from Nexperia is an automotive-qualified quad 2-input NOR gate in TSSOP14 package, operating from -40 °C to +125 °C with TTL-level inputs, 5.5 V max supply, and propagation delay as low as 3.8 ns (CL = 15 pF, VCC = 5 V). It delivers balanced timing, Schmitt-trigger inputs, and input overvoltage tolerance for robust logic interfacing in engine control units and ADAS sensor signal conditioning.

For engineers reviewing the 74AHCT02PW-Q100 datasheet, 74AHCT02PW-Q100 pinout, 74AHCT02PW-Q100 application, or 74AHCT02PW-Q100 equivalent, key selection criteria include automotive AEC-Q100 Grade 1 qualification, TTL-compatible input thresholds, guaranteed operation up to +125 °C ambient, and verified dynamic performance under 15–50 pF capacitive loads.

Technical Context

This device implements four independent 2-input NOR gates using high-speed Si-gate CMOS technology, fully compliant with JEDEC Standard No. 7-A and pin-compatible with LSTTL. Its TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) enable direct interfacing with legacy 5 V logic families without level shifting.

All inputs feature Schmitt-trigger action for noise immunity and accept voltages up to 7.0 V regardless of VCC, while outputs drive ±8.0 mA at VCC = 4.5 V with VOH ≥ 3.70 V and VOL ≤ 0.55 V across the full temperature range.

FAQ

What is the maximum input voltage the 74AHCT02PW-Q100 can tolerate?

The device accepts input voltages up to +7.0 V regardless of VCC level, as specified in Table 4 (Limiting Values). This overvoltage tolerance applies to all input pins (1A–4B) and eliminates the need for external clamping diodes when interfacing with 12 V automotive signals or hot-plug detection circuits.

Does the 74AHCT02PW-Q100 support operation at 3.3 V supply?

No - the 74AHCT02PW-Q100 is specified only for VCC = 4.5 V to 5.5 V per Table 5. Its TTL-compatible input thresholds require minimum 4.5 V to guarantee VIH ≥ 2.0 V and VIL ≤ 0.8 V. For 3.3 V systems, consider the 74AHC02PW-Q100 variant instead.

How does the Schmitt-trigger input improve noise immunity?

Each input exhibits hysteresis of approximately 0.5 V at VCC = 5 V, meaning the rising threshold (VIH) is ~2.0 V and falling threshold (VIL) is ~1.5 V. This prevents multiple toggles during slow or noisy signal transitions - critical for reliable decoding of PWM signals from throttle position sensors or LIN bus wake-up pulses.

Is the TSSOP14 package compatible with reflow soldering per J-STD-020?

Yes - the SOT402-1 package is qualified for standard lead-free reflow profiles (peak temperature 260 °C, 20–40 s above 217 °C). Its side-wettable flanks support automated optical inspection of solder joint quality, satisfying IPC-A-610 Class 3 requirements for automotive production.
