That hysteresis cleans up noisy or slow-rising input signals — a common failure signature on boards where a sensor line or switch contact bounces and the gate sees an indeterminate logic level. ## Supply voltage, temperature, and output drive Operates from 2V to 6V single supply, covering 3.3V and 5V logic rails common in automotive ECUs. Quiescent current max is 2 µA — negligible for battery-backed or always-on modules. Output drive is 7.8 mA source and sink at rated voltage — enough to switch a downstream logic input or a small LED indicator, but not a relay coil. Propagation delay is 16 ns max at 6V with a 50 pF load, so the gate handles bus speeds up to tens of MHz without timing margin issues. If a board was laid out for a 14-pin SOIC AND gate, this part drops in without a layout spin. The AEC-Q100 automotive grade means the part carries the full PPAP documentation package — traceable date codes, qualification test reports, and PCN notification if anything changes. For a repair bench, that means the replacement you order today matches the original spec.","metaTitle":"SN74HCS11QDRQ1 Texas Instruments Triple 3-Input AND Gate","metaDescription":"Texas Instruments SN74HCS11QDRQ1 triple 3-input AND gate with Schmitt-trigger inputs.
