FST3253 - Dual 4:1 Multiplexer/Demultiplexer Bus Switch

Download the FST3253 datasheet PDF. This datasheet also covers the FST variant, as both devices belong to the same dual 4:1 multiplexer/demultiplexer bus switch family and are provided as variant models within a single manufacturer datasheet.

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.

Features

  • s 4Ω switch connection between two ports. s Minimal propagation delay through the switch. s Low lCC. s Zero bounce in flow-through mode. s Control inputs compatible with TTL level. Ordering Code: Order Number FST3253M FST3253QSC FST3253MTC Package Number M16A MQA16 MTC16 Package.

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