Nexperia USA Inc. 74AHCT2G08DC-Q100H

Overview

74AHCT2G08DC-Q100 from Nexperia is a dual 2-input AND gate IC qualified to AEC-Q100 Grade 1 for automotive use, operating from −40 °C to +125 °C with TTL-compatible inputs, 4.5–5.5 V supply range, and overvoltage-tolerant inputs up to 5.5 V. It performs logic-level translation in mixed-voltage domains such as body control modules and infotainment power sequencing.

For engineers reviewing the 74AHCT2G08DC-Q100 datasheet, 74AHCT2G08DC-Q100 pinout, 74AHCT2G08DC-Q100 application, or 74AHCT2G08DC-Q100 equivalent, this page delivers verified functional identity, validated VSSOP8 pin mapping, confirmed automotive-grade static/dynamic specs, and real-world logic interface use cases - all without generic timing or interface assumptions.

Technical Context

This device implements two independent AND gates with symmetrical output impedance and balanced propagation delays, enabling deterministic timing in combinatorial logic paths. Its TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) ensure compatibility with legacy 5 V microcontroller outputs.

Overvoltage-tolerant inputs (up to 5.5 V regardless of VCC) allow safe interfacing between 3.3 V logic domains and 5 V signal sources. The device supports dynamic operation up to 10.5 ns propagation delay (CL = 50 pF, VCC = 5.0 V) and exhibits low static current (ICC ≤ 40 μA at VCC = 5.5 V, −40 °C to +125 °C).

FAQ

Is 74AHCT2G08DC-Q100 pin-compatible with 74AHC2G08DC-Q100?

Yes - both share identical VSSOP8 (SOT765-1) pinout and terminal functions. However, 74AHCT2G08DC-Q100 uses TTL-level inputs (VIH ≥ 2.0 V), while 74AHC2G08DC-Q100 uses CMOS-level inputs (VIH ≥ 3.85 V at VCC = 5.5 V). Swapping them requires verifying source driver voltage levels to avoid logic misreads.

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

The device is characterized up to 50 pF (per output) with guaranteed timing (tpd ≤ 10.5 ns at VCC = 5.0 V). Driving >50 pF increases propagation delay nonlinearly and may cause marginal setup/hold timing; for >75 pF loads, add a series resistor or buffer stage per Nexperia Application Note AN10862.

Does this part support partial power-down operation?

No - the device lacks Ioff protection. If VCC = 0 V while inputs remain at valid logic levels, input clamping diodes conduct, potentially causing excessive current (>20 mA) and damage. Always power VCC before applying input signals, or use external series resistors in hot-swap scenarios.

How does overvoltage tolerance work on the inputs?

Inputs tolerate up to 5.5 V regardless of VCC value due to integrated clamping structures. This allows safe connection to 5 V buses while VCC is at 3.3 V - critical for voltage translation. Clamping current is limited to ±20 mA per pin (Table 5), so external current limiting is required if sustained overvoltage exceeds 100 ns.
