Description
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.

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
• 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 plastic TSSOP (L)
