Nexperia USA Inc. 74AHCT08PW,118

Overview

74AHCT08PW,118 from Nexperia is a quad 2-input AND gate IC with TTL-compatible input thresholds, 4.5 V to 5.5 V supply operation, 7.5 ns typical propagation delay at 5 V/50 pF, overvoltage-tolerant inputs up to 5.5 V, and TSSOP14 packaging for space-constrained logic interfacing in industrial control panels.

For engineers reviewing the 74AHCT08PW,118 datasheet, 74AHCT08PW,118 pinout, 74AHCT08PW,118 application, or 74AHCT08PW,118 equivalent, this device serves as a level-translating combinational logic element in mixed-voltage digital systems requiring robust noise immunity, Schmitt-trigger input hysteresis, and guaranteed operation from –40 °C to +125 °C.

Technical Context

The 74AHCT08PW,118 implements four independent AND gates in a single monolithic CMOS structure with TTL-level input recognition (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interface with legacy 5 V TTL outputs without external level shifters.

Its overvoltage-tolerant inputs accept signals up to 5.5 V regardless of VCC, supporting use as a voltage-domain translator between 3.3 V and 5 V subsystems; all inputs feature Schmitt-trigger action for improved noise rejection on slow or noisy signal edges.

FAQ

Can 74AHCT08PW,118 operate with a 3.3 V supply?

No. The 74AHCT08PW,118 is specifically designed for TTL-level input compatibility and requires a minimum VCC of 4.5 V. Its VIH threshold is fixed at 2.0 V min, but operation below 4.5 V violates recommended conditions and risks undefined output behavior. For 3.3 V systems, use the pin-compatible 74AHC08PW,118 variant instead.

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

The 74AHCT08PW,118 is characterized up to 50 pF load capacitance with guaranteed timing (tPD ≤ 10.0 ns). Driving >50 pF increases propagation delay nonlinearly and may cause output ringing; for loads exceeding 50 pF, add a series resistor (22–47 Ω) near the output pin to dampen reflections and maintain signal integrity.

Does this part have internal ESD protection on all pins?

Yes. The 74AHCT08PW,118 includes on-chip ESD protection meeting ANSI/ESDA/JEDEC JS-001 Class 2 (HBM ≥ 2000 V) and JS-002 Class C3 (CDM ≥ 1000 V) standards on all I/O pins. No external protection diodes are required for typical handling and board-level ESD events, though system-level protection remains advisable in harsh environments.

How does the Schmitt-trigger input affect timing analysis?

The Schmitt-trigger action adds ~1.2 ns to the input transition time but eliminates metastability from slow-rising signals. For timing analysis, use the specified tPLH/tPHL values (7.0 ns typ at 5 V/15 pF) - these already include Schmitt delay. Input rise/fall rates slower than 20 ns/V do not degrade output timing, unlike standard CMOS inputs.
