FSTU3257QSC Datasheet PDF - Fairchild

●General Description

●The Fairchild Switch FSTU3257 is a quad 2:1 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

●■ Undershoot hardened to 2V (A and B Ports)

●■ Soft enable turn-on to minimize bus to bus charge sharing during enable

●■ 4: 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.

●■ See Applications Note AN-5008 for details
