Nexperia USA Inc. 74AHC1G02GV-Q100H

Overview

74AHC1G02GV-Q100 from Nexperia is a single 2-input automotive-grade NOR gate in SC-74A (SOT753) package, operating from 2.0 V to 5.5 V supply, with overvoltage-tolerant inputs up to 5.5 V and AEC-Q100 Grade 1 qualification for under-hood control logic.

For engineers reviewing the 74AHC1G02GV-Q100 datasheet, 74AHC1G02GV-Q100 pinout, 74AHC1G02GV-Q100 application, or 74AHC1G02GV-Q100 equivalent, this device serves as a voltage-translating logic gate in mixed-supply automotive subsystems requiring robust noise immunity, symmetrical output drive, and -40 °C to +125 °C operation.

Technical Context

This CMOS NOR gate implements standard positive-logic NOR function (Y = NOT(A OR B)) with TTL-compatible input thresholds only in the AHCT variant; the AHC variant uses CMOS-level inputs referenced to VCC. Input clamping and ESD protection meet HBM >2000 V and CDM >1000 V per JEDEC JS-001/JS-002.

Propagation delay is specified at 3.2 ns (typ, VCC = 5.0 V, CL = 15 pF) with balanced tPLH/tPHL, symmetrical output impedance, and latch-up immunity exceeding 100 mA per JESD78 Class II Level A. Power dissipation capacitance is 18 pF at 1 MHz.

FAQ

Is 74AHC1G02GV-Q100 pin-compatible with 74AHCT1G02GV-Q100?

Yes - both share identical SC-74A (SOT753) package, 5-pin layout, and pin functions (A, B, GND, Y, VCC). The only functional difference is input threshold behavior: AHC uses CMOS-level inputs (VIH ≈ 0.7×VCC), while AHCT uses fixed TTL thresholds (VIH = 2.0 V min). No PCB redesign is needed for substitution.

What is the maximum capacitive load this NOR gate can drive reliably?

The device is characterized up to 50 pF load capacitance with guaranteed propagation delay (≤7.0 ns at VCC = 5.5 V). For loads exceeding 50 pF, rise/fall times increase linearly; derating is required beyond 100 pF to maintain timing margins. Output current remains within ±8 mA limits up to CL = 100 pF at 1 MHz.

Does this part support partial power-down operation with floating inputs?

No - inputs must never be left floating. The datasheet mandates termination to VCC or GND when unused. Floating inputs cause increased ICC, unpredictable output states, and potential shoot-through current. Unused inputs should be tied directly to VCC or GND using short traces; series resistors are not recommended.

Can 74AHC1G02GV-Q100 operate at 2.0 V supply while interfacing with 3.3 V logic?

Yes - its overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC. At VCC = 2.0 V, it correctly interprets 3.3 V inputs as HIGH (VIH min = 1.5 V), and outputs swing rail-to-rail (0 V / 2.0 V), making it ideal for translating from higher-voltage domains into low-power 2.0 V subsystems.
