Nexperia USA Inc. 74AHC1G09GW-Q100H

Overview

74AHC1G09GW-Q100 from Nexperia is a single 2-input AND gate with open-drain output, 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 and overvoltage-tolerant inputs up to 5.5 V. It enables level translation in mixed-voltage domains such as CAN/LIN interface pull-up networks or I²C bus arbitration logic.

For engineers reviewing the 74AHC1G09GW-Q100 datasheet, 74AHC1G09GW-Q100 pinout, 74AHC1G09GW-Q100 application, or 74AHC1G09GW-Q100 equivalent, key selection criteria include open-drain drive capability, automotive temperature compliance, input overvoltage tolerance, propagation delay under 9.0 ns at 5.5 V/50 pF, and TSSOP5 package compatibility with automated optical inspection (AOI) and reflow profiles.

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 CMOS input structure provides rail-to-rail voltage recognition and high noise immunity (>200 mV hysteresis typical), while the output supports bidirectional wired-AND configurations.

The logic function follows H = HIGH, L = LOW, Z = high-impedance OFF-state: only when both inputs A and B are HIGH does the output Y transition to low-impedance LOW; all other input combinations result in high-impedance output. Input clamping current is rated ±20 mA, supporting robust transient suppression in noisy automotive environments.

FAQ

Can the 74AHC1G09GW-Q100 drive a 10 kΩ pull-up resistor on a 5 V bus?

Yes. With VOL ≤ 0.55 V at IO = 8.0 mA (VCC = 4.5 V), the output sinks sufficient current to maintain logic LOW when driving a 10 kΩ pull-up on 5 V - resulting in ~0.55 V output voltage, well within standard TTL/CMOS LOW thresholds. Derating applies above 85 °C ambient.

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

Yes. The open-drain output cannot source current; a pull-up resistor to a defined voltage rail (e.g., 3.3 V or 5 V) is mandatory to establish the logic HIGH state. Typical values range from 2.2 kΩ to 10 kΩ depending on bus capacitance and rise-time requirements.

Does this device support hot insertion or live bus connection?

No. While inputs tolerate overvoltage up to 5.5 V, the device lacks explicit hot-swap protection circuitry. Connecting to a live bus before VCC is applied may cause latch-up or parametric shift. Power sequencing - VCC first, then signal - is required per AEC-Q100 design guidelines.

What is the maximum capacitive load the output can drive reliably?

The datasheet specifies dynamic performance up to 50 pF load capacitance with guaranteed propagation delay (≤9.0 ns). For loads exceeding 50 pF, rise time increases linearly with capacitance; designs requiring >100 pF should add a buffer stage or reduce pull-up resistance to maintain timing margins.
