Nexperia USA Inc. 74AHC2G08DP-Q100H

Overview

74AHC2G08DP-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 supply voltage range 2.0–5.5 V, overvoltage-tolerant inputs up to 5.5 V, and CMOS-level input compatibility. It performs basic logic conjunction in signal routing, enable control, and bus gating functions within engine control units and ADAS sensor interfaces.

For engineers reviewing the 74AHC2G08DP-Q100 datasheet, 74AHC2G08DP-Q100 pinout, 74AHC2G08DP-Q100 application, or 74AHC2G08DP-Q100 equivalent, this device supports mixed-voltage translation, requires attention to propagation delay (≤8.0 ns at VCC = 5.0 V, CL = 15 pF), output drive capability (±8 mA), input threshold behavior (VIH = 3.85 V min at VCC = 5.5 V), and thermal derating above 96 °C in TSSOP8 packaging.

Technical Context

This device implements two independent AND logic gates in a single monolithic CMOS structure, with symmetrical output impedance and balanced tPLH/tPHL propagation delays ensuring deterministic timing across both channels. Its overvoltage-tolerant inputs accept signals up to 5.5 V regardless of VCC level, enabling direct interfacing between 3.3 V and 5.0 V domains without external level shifters.

The 74AHC2G08DP-Q100 uses standard CMOS input thresholds referenced to VCC (VIH ≥ 0.7×VCC, VIL ≤ 0.3×VCC), delivering high noise immunity (typical 1.0 V noise margin at VCC = 5.0 V) and low static current (ICC ≤ 40 μA at VCC = 5.5 V, -40 °C to +125 °C). It complies with JEDEC JESD78 Class II Level A latch-up immunity (>100 mA) and ESD ratings per JS-001 (2000 V HBM) and JS-002 (1000 V CDM).

FAQ

Is 74AHC2G08DP-Q100 pin-compatible with 74AHC2G08DC-Q100?

Yes - both share identical pin assignment (1A, 1B, 2Y, GND, 2A, 2B, 1Y, VCC) and logic function, differing only in package: SOT505-2 (TSSOP8, 3 mm body) versus SOT765-1 (VSSOP8, 2.3 mm body). PCB layout must accommodate footprint differences, but schematic symbols and net connectivity remain interchangeable.

What is the maximum allowable junction temperature for continuous operation?

The absolute maximum junction temperature is +150 °C per IEC 60134 limiting values. With TSSOP8 package thermal resistance θJA ≈ 130 K/W and Ptot = 250 mW at Tamb ≤ 96 °C, sustained operation at full power requires Tamb ≤ 117 °C to stay below Tj = 150 °C. Derating begins linearly above 96 °C at 4.6 mW/K.

Can this device interface directly between a 3.3 V microcontroller and a 5 V sensor?

Yes - its overvoltage-tolerant inputs accept 0–5.5 V signals regardless of VCC level. When powered at 3.3 V, it safely reads 5 V sensor outputs without clamping diodes or external resistors, while its 3.3 V CMOS-compatible outputs remain compatible with other 3.3 V receivers.

Does this part support hot insertion or live swapping in powered systems?

No - the datasheet does not specify hot-swap capability. Inputs lack dedicated hot-swap protection circuitry, and applying VCC after signal assertion may violate absolute maximum ratings (e.g., VI > VCC + 0.5 V). Power sequencing must ensure VCC is stable before applying input signals.
