Nexperia USA Inc. 74AHC1G02GW-Q100H

Overview

74AHC1G02GW-Q100 from Nexperia is a single 2-input automotive-grade NOR gate in TSSOP5 (SOT353-1) package, operating from 2.0 V to 5.5 V supply, with overvoltage-tolerant inputs up to 5.5 V and guaranteed operation from −40 °C to +125 °C. It serves as a level-translating logic element in mixed-voltage domains within body control modules and powertrain interface circuits.

For engineers reviewing the 74AHC1G02GW-Q100 datasheet, 74AHC1G02GW-Q100 pinout, 74AHC1G02GW-Q100 application, or 74AHC1G02GW-Q100 equivalent, key selection criteria include input voltage compatibility (CMOS-level), propagation delay under 7.0 ns at 5 V/50 pF, AEC-Q100 Grade 1 qualification, and symmetrical output drive capability for noise-immune signal inversion.

Technical Context

This device implements a standard two-input NOR Boolean function with fully buffered CMOS inputs and push-pull outputs. Its overvoltage-tolerant inputs enable direct interfacing between 3.3 V logic domains and 5 V subsystems without external level shifters.

It features symmetrical output impedance and balanced propagation delays (tPLH ≈ tPHL), ensuring minimal duty-cycle distortion in timing-critical paths. The latch-up immunity exceeds 100 mA per JESD78 Class II Level A, supporting robust operation in electrically noisy automotive environments.

FAQ

Is 74AHC1G02GW-Q100 pin-compatible with 74AHCT1G02GW-Q100?

Yes - both share identical TSSOP5 (SOT353-1) pinout, mechanical dimensions, and thermal characteristics. The only functional difference is input threshold voltage: 74AHC1G02GW-Q100 requires CMOS-level inputs (VIH ≥ 3.85 V at VCC = 5.5 V), while 74AHCT1G02GW-Q100 accepts TTL-level inputs (VIH ≥ 2.0 V). No PCB redesign is needed for substitution.

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

The device is characterized up to 50 pF load capacitance with guaranteed propagation delay ≤ 7.0 ns at VCC = 5.0 V. Driving >50 pF increases delay nonlinearly and may cause marginal timing in high-speed paths; for >100 pF loads, add a buffer stage or verify timing margin using the CPD = 18 pF value in dynamic power calculations.

Can this NOR gate operate with VCC = 2.5 V while accepting 3.3 V inputs?

Yes - its overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC level. At VCC = 2.5 V, VIH is specified at 1.75 V (70% of VCC), so a 3.3 V input safely exceeds that threshold and will be recognized as HIGH, enabling mixed-supply translation without damage or logic error.

Does this part support hot-swap or live-insertion in automotive modules?

No - it lacks explicit hot-swap protection circuitry such as slew-rate controlled outputs or input current limiting. While its overvoltage tolerance prevents damage from floating inputs during insertion, uncontrolled power sequencing may cause transient glitches or latch-up if VCC ramps after inputs. Use with controlled power-up sequencing or external series resistors in live-insertion scenarios.
