FSTU3257QSC集成电路（IC）的信号开关多路复用器解码器规格书PDF中文资料

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.

特性 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
