The open-drain output sinks 7.8 mA per channel. AEC-Q100 qualification is the primary sourcing gate for this part. The -40°C to 125°C operating range covers underhood and engine-bay environments. ## Open-drain outputs and wired-AND configuration The open-drain output stage lets multiple gate outputs connect to a common pull-up resistor, forming a wired-AND bus. Input logic levels scale with supply: a low threshold of 1V to 3V and a high threshold of 1.5V to 4.2V over the 2V to 6V supply range. ## Lifecycle and sourcing posture ROHS3 compliant. The Q1 suffix denotes the automotive-qualified variant with PPAP documentation available. ## Timing and signal integrity Maximum propagation delay is 11 ns at 6V supply with 50 pF load. Quiescent current is 2 µA maximum.","metaTitle":"SN74HCS09QDRQ1 Automotive AND Gate, AEC-Q100, 2V-6V, 14-SOIC","metaDescription":"TI SN74HCS09QDRQ1 quad 2-input AND gate with open-drain outputs, Schmitt-trigger inputs.

For a pin-compatible AND gate alternative within the same family, there is no direct second-source listed.
