Nexperia USA Inc. 74AHC1G09GV-Q100H

Overview

74AHC1G09GV-Q100 from Nexperia is a single 2-input AND gate with open-drain output, qualified to AEC-Q100 Grade 1 for automotive use. It operates across -40 °C to +125 °C, supports 2.0–5.5 V supply, features overvoltage-tolerant inputs up to 5.5 V, and delivers propagation delay as low as 3.2 ns (VCC = 5.0 V, CL = 15 pF). It enables level translation in mixed-voltage automotive body control modules.

For engineers reviewing the 74AHC1G09GV-Q100 datasheet, 74AHC1G09GV-Q100 pinout, 74AHC1G09GV-Q100 application, or 74AHC1G09GV-Q100 equivalent, key selection criteria include open-drain drive capability, input overvoltage tolerance, automotive temperature range compliance, and SC-74A (SOT753) package compatibility with high-density PCB layouts.

Technical Context

This device implements standard AND logic with an open-drain output stage, requiring an external pull-up resistor to define HIGH-level voltage and current sourcing. Its overvoltage-tolerant inputs accept signals up to 5.5 V independent of VCC, enabling bidirectional level shifting between 3.3 V and 5.0 V domains.

The logic function follows H = HIGH, L = LOW, Z = high-impedance OFF-state: only when both inputs are HIGH does the output enter low-impedance LOW state; otherwise, it remains high-impedance. Static and dynamic characteristics are fully specified across -40 °C to +125 °C, with VOL ≤ 0.55 V at IO = 8.0 mA and VCC = 4.5 V.

FAQ

What is the maximum allowable output sink current for 74AHC1G09GV-Q100?

The absolute maximum output current is ±25 mA per the limiting values table. However, recommended operating conditions specify a maximum output current of 8.0 mA for VOL ≤ 0.55 V at VCC = 4.5 V. Sustained operation above 8.0 mA may exceed thermal limits in the SC-74A package, especially at +125 °C ambient.

Can 74AHC1G09GV-Q100 interface a 5 V sensor output with a 3.3 V microcontroller input?

Yes - its inputs tolerate up to 5.5 V regardless of VCC, so it can accept 5 V sensor signals while powered from 3.3 V. The open-drain output must be pulled up to the microcontroller's I/O voltage (e.g., 3.3 V), ensuring compatible logic HIGH levels without additional components.

Is an external pull-up resistor required for normal operation?

Yes - the open-drain output cannot source current; a pull-up resistor is mandatory to establish a defined HIGH logic level. Typical values range from 1 kΩ (for speed-critical 10 MHz buses) to 10 kΩ (for low-power wake-up detection), selected based on rise time, bus capacitance, and drive strength requirements.

Does 74AHC1G09GV-Q100 support hot-swap or live-insertion?

No - the device lacks explicit hot-swap protection circuitry. While its overvoltage-tolerant inputs improve resilience, applying VCC after inputs are driven may cause latch-up or excessive current through internal clamping diodes. Power sequencing (VCC before inputs) is required per JESD78 Class II Level A compliance.
