Description
Pericom Semiconductor’s PI5C3257 is a Quad 2:1 multiplexer/
demultiplexer with three-state outputs that is pinout and function
compatiblewiththePI74FCT257T,74F257,and74ALS/AS/LS257.
Inputs can be connected to outputs with low On-Resistance (5)
with no additional ground bounce noise or propagation delay.
Block Diagram
Features:
Near-Zero propagation delay
5 switches connect inputs to outputs
Direct bus connection when switches are ON
Ultra Low Quiescent Power (0.2A typical)
– Ideally suited for notebook applications
Pin compatible with 74 series 257 logic devices
Packaging (Pb-free & Green available):
– 16-pin 150-mil wide plastic QSOP (Q)
– 16-pin 150-mil wide plastic SOIC (W)
– 16-pin 173-mil wide plasticTSSOP (L)
