3.3V, Dual 4:1
Mux/DeMux NanoSwitch™
Description
Pericom Semiconductor’s PI3B3253 is a 3.3V, Dual4:1 Multi-
plexer/ 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.
