Description

Pericom Semiconductor’s PI5C3125 and PI5C3126 are 4-bit Bus Switches designed with four individual 5Ω bus switches with fast individual enables in an industry standard 74XX125/126 pinout. When enabled via the associated Bus Enable (BE) pin, the “A” pin is directly connected to the “B” pin for that particular gate. The bus switch introduces no additional propagation delay or additional ground bounce noise. The PI5C3125 device has active LOW enables, and the PI5C3126 has active HIGH enables.

Specifications and Features

• Near-Zero propagation delay
• 5Ω switches connect inputs to outputs
• Direct bus connection when switches are ON
• Ultra Low Quiescent Power (0.1µA typical) - Ideally suited for notebook applications
• Packaging (Pb-free & Green available): 16-pin 150-mil wide plastic QSOP (Q)

Application Scenarios

The PI5C3126QE model can be used in various electronic devices and systems that require signal switches, encoders, decoders, or multiplexers. Examples include notebook computers, data communication systems, telecommunications equipment, and other industrial electronic equipment.
