SN74AHCT1G126/SN74AHCT1G126-Q1 Bus Buffer Gates

Texas Instruments SN74AHCT1G126/SN74AHCT1G126-Q1 Single Bus Buffer Gates are bus buffer gates/line drivers with a 3-state output. When the output-enable (OE) input is low, the output is disabled. When OE is high, true data is passed from the A input to the Y output. The Texas Instruments SN74AHCT1G126-Q1 devices are AEC-Q100 qualified for automotive applications.
