PI5C3253, Dual 4:1 Mux/DeMux Bus Switch

Pericom Semiconductor’s PI5C3253 is a Dual 4:1 Multiplexer/ demultiplexer with three-state outputs that is pinout compatible 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.

PI5C3253 Features

* Near-Zero propagation delay

* 5Ω switches connect inputs to outputs

* Direct bus connection when switches are ON

* Ultra Low Quiescent Power (0.2µA Typical)

* Ideally suited for notebook applications

* Pin compatible with 74 series 253 logic devices
