FST3253 Dual 4:1 Multiplexer/Demultiplexer Bus Switch September 1997 Revised December 1999 FST3253 Dual 4:1 Multiplexer/Demultiplexer Bus Switch General Description The Fairchild Switch FST3253 is a dual 4:1 high-speed CMOS TTL-patible 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, S0 and S1 connect 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. Features s 4Ω switch connection between two ports. s Minimal propagation delay through the...
