Quad 2:1 Multiplexer/

Demultiplexer Bus Switch

The ON Semiconductor 74FST3257 is a quad 2:1, high performance

multiplexer/demultiplexer bus switch. The device is CMOS TTL

compatible when operating between 4 and 5.5 Volts. The device

exhibits extremely low RON and adds nearly zero propagation delay.

The device adds no noise or ground bounce to the system.

Features

• RON t 4 W Typical

• Less Than 0.25 ns−Max Delay Through Switch

• Nearly Zero Standby Current

• No Circuit Bounce

• Control Inputs are TTL/CMOS Compatible

• Pin−For−Pin Compatible With QS3257, FST3257, CBT3257

• All Popular Packages: SOIC−16, TSSOP−16, QFN16

• These Devices are Pb−Free and are RoHS Compliant
