FST3257 switch equivalent, quad 2:1 multiplexer / demultiplexer bus switch.
4Ω Switch Connection Between Two Ports Minimal Propagation Delay Through the Switch Low ICC Zero Bounce in Flow-Through Node Control Inputs Compatible with TTL .
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 g.
