Descriptions
Descriptions of onsemi FST3257MX provided by its distributors.
FST3257 Series 5.5 V Quad 2:1 Multiplexer/Dumultiplexer Bus Switch - SOIC-16
Multiplexer/Demultiplexer Bus Switch 1-Element CMOS 8-IN 16-Pin SOIC N T/R

CBT/FST/QS/5C/B e3 3257 4x 2:1 multiplexer circuit 9.9ns 5V 9.9mm 3muA
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.
