PI5C3253 Datasheet Dual 4:1 Mux/demux Bus Switch

Manufacturer: Pericom Semiconductor (now Diodes Incorporated)

Overview: PI5C3253 Dual 4:1 Mux/DeMux Bus Switch.

General Description

Peri Semiconductor’s PI5C3253 is a Dual 4:1 Multiplexer/ demultiplexer with three-state outputs that is pinout patible with the PI74FCT253T, 74F253, and 74ALS/AS/LS 253.

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