PI3B3253 Datasheet (Pericom Semiconductor Corporation)

PI3B3253, Mux/DeMux NanoSwitch

Pericom Semiconductor’s PI3B3253 is a 3.3V, Dual4:1 Multiplexer/ Demultiplexer with Hi-Z 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.

PI3B3253 Features

* Near-Zero propagation delay

* 5Ω switches connect inputs to outputs

* Fast Switching Speed: 5.2ns max. Ultra Low Quiescent Power (0.2µA typical)

* Ideally suited for notebook applications Pin compatible with 74 series 253 logic devices Descripti
