FSTU3257 - Quad 2:1 Multiplexer/Demultiplexer Bus Switch with -2V Undershoot Protection
The Fairchild Switch FSTU3257 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.
