PI5C3251 Datasheet 8:1 Mux/demux Busswitch

Manufacturer: Pericom Semiconductor (now Diodes Incorporated)

General Description

: Peri Semiconductor’s PI5C3251 is a Dual 8:1 Multiplexer/ Demultiplexer with three-state outputs that is pinout patible with the PI74FCT251T, 74F251, and 74ALS/AS/LS 251.

Inputs can be connected to outputs with low on resistance (5Ω) with no additional ground bounce noise or propagation delay.
