FST3253MTCX Datasheet

Dual 4:1 Multiplexer/Demultiplexer Bus Switch


General Description
The Fairchild Switch FST3253 is a dual 4:1 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, 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.

■ 4Ω switch connection between two ports.
■ Minimal propagation delay through the switch.
■ Low lCC.
■ Zero bounce in flow-through mode.
■ Control inputs compatible with TTL level.
