FST3253 Datasheet Dual 4:1 Multiplexer/demultiplexer Bus Switch

Manufacturer: Fairchild (now onsemi)

Overview: FST3253 Dual 4:1 Multiplexer/Demultiplexer Bus Switch September 1997 Revised December 1999 FST3253 Dual 4:1 Multiplexer/Demultiplexer Bus.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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.

Key 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.
