SN74HCS125/SN74HCS125-Q1 Quadruple Bus Buffer

Texas Instruments SN74HCS125/SN74HCS125-Q1 Quadruple Bus Buffer contains four independent buffers with 3-state outputs and Schmitt-trigger inputs. Each buffer performs the Boolean function Y = A in positive logic. The outputs can be put into a Hi-Z state by applying a High on the OE pin. The Texas Instruments SN74HCS125-Q1 devices are AEC-Q100 qualified for automotive applications.
