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.

Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 3.3V, TA = 25°C ambient and maximum loading.
3. Measured by the voltage drop between I and Y pin at indicated current through the switch. On-Resistance is determined by the lower of the
voltages on the two (I,Y) pins.
4. This parameter is determined by device characterization but is not production tested.
