FST3253 Dual 4:1 Multiplexer/Demultiplexer Bus Switch September 1997 Revised December 1999 FST3253 Dual 4:1 Multiplexer/Demultiplexer Bus Switch General Description Features The Fairchild Switch FST3253 is a dual 4:1 high-speed4Ω switch connection between two ports. CMOS TTL-compatible multiplexer/demultiplexer busMinimal propagation delay through the switch. switch. The low on resistance of the switch allows inputs to Low l . CC be connected to outputs without adding propagation delay Zero bounce in flow-through mode. or generating additional ground bounce noise. Control inputs compatible with TTL level. When OE is LOW, S and S connect the A Port to the 0 1 selected B Port output. When OE is HIGH, the switch is OPEN and a high-impedance state exists between the two ports.
