Texas Instruments SN74AC157-Q1 2-1-Line Data Selectors/Multiplexers

Texas Instruments SN74AC157-Q1 2-Line to 1-Line Automotive Quadruple Data Selectors/Multiplexers are high-speed silicon-gate CMOS multiplexers designed for multiplexing and data routing applications. These devices contain four 2-line to 1-line multiplexers/data selectors with shared control logic. The SN74AC157-Q1 multiplexers operate at a 1.5V to 6V supply voltage range, up to 6V inputs accept voltages, and a continuous ±24mA output drive at 5V. These multiplexers support up to ±75mA output drive at 5V in short bursts, drive 50Ω transmission lines, and a maximum tpd of 7.3ns at 5V, 50pF load. The SN74AC157-Q1 devices are AEC-Q100 qualified for automotive applications.
