MUX/DEMUX, 4 CH, 2: 1, TSSOP-16; Logic Family / Base Number: FST3257; Logic Type: Multiplexer / Demultiplexer Bus Switch; No. of Channels: 4Channels; Line Configuration: 2: 1; Supply Volta; Available until stocks are exhausted
The Fairchild Switch FST3257 is a quad 2:1 high-speed CMOS TTL-compatible multiplexer / demultiplexer bus switch. The low on resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. When /OE is LOW, the select pin connects the A port to the selected B port output. When /OE is HIGH, the switch is OPEN and a high-impedance state exists between the two ports.
