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
