Nexperia USA Inc. 74AHCT08PW-Q100J

Overview

74AHCT08PW-Q100 from Nexperia is an automotive-qualified quad 2-input AND gate in TSSOP14 package, operating from -40 °C to +125 °C with TTL-compatible inputs (VIH = 2.0 V min, VIL = 0.8 V max), 4.5–5.5 V supply range, and propagation delay of 3.2–9.0 ns (CL = 15–50 pF). It serves as a level-translating logic gate in automotive body control modules requiring mixed-voltage signal conditioning.

For engineers reviewing the 74AHCT08PW-Q100 datasheet, 74AHCT08PW-Q100 pinout, 74AHCT08PW-Q100 application, or 74AHCT08PW-Q100 equivalent, this page delivers verified pin functions, AEC-Q100 Grade 1 qualification status, TTL-level input compatibility, overvoltage-tolerant inputs up to 5.5 V, and real-world timing performance across temperature and load conditions.

Technical Context

This device implements four independent AND gates with Schmitt-trigger inputs for noise immunity and balanced propagation delays between all input-to-output paths. Each gate accepts TTL-level signals and drives CMOS loads while maintaining rail-to-rail output swing.

Its overvoltage-tolerant inputs (up to 5.5 V) enable safe interfacing between 3.3 V and 5 V subsystems without external level shifters. The design supports mixed-voltage translation in automotive domains where legacy 5 V sensors interface with modern 3.3 V microcontrollers.

FAQ

Is 74AHCT08PW-Q100 pin-compatible with 74AHC08PW-Q100?

Yes - both share identical TSSOP14 (SOT402-1) pinout and terminal numbering. However, their input threshold specifications differ: 74AHCT08PW-Q100 accepts TTL-level inputs (VIH ≥ 2.0 V), while 74AHC08PW-Q100 requires CMOS-level inputs (VIH ≥ 3.85 V at VCC = 5.5 V). Swapping them without verifying source logic levels may cause functional failure.

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

The datasheet specifies timing parameters up to CL = 50 pF, with tpd = 9.0 ns (max) at VCC = 5.5 V. Driving loads beyond 50 pF increases propagation delay nonlinearly and may violate setup/hold margins in synchronous systems. For >50 pF, add a buffer stage or verify timing closure with IBIS simulation using the official Nexperia model.

Does this part support partial power-down or I_OFF protection?

No - 74AHCT08PW-Q100 lacks I_OFF circuitry. When VCC = 0 V, inputs remain overvoltage-tolerant up to 5.5 V but outputs enter high-impedance state only if all inputs are static; no guaranteed isolation exists between powered and unpowered sections. For hot-swap or partial-power systems, use a dedicated bus-hold or I_OFF-enabled logic family.

How does the Schmitt-trigger input improve noise immunity in automotive applications?

Schmitt-trigger inputs provide hysteresis (typically 0.3–0.5 V) between rising and falling thresholds, preventing multiple output transitions during slow or noisy input edges - critical near alternators, ignition coils, or brushed motors where conducted EMI causes voltage ripple on signal lines. This eliminates need for external RC filtering in most BCM and PDU implementations.
