PI5C3251 - 8:1 Mux/DeMux BusSwitch

General Description

Pericom Semiconductor’s PI5C3251 is a Dual 8:1 Multiplexer/ Demultiplexer with three-state outputs that is pinout compatible 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.

Key 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.
