Product Description
Pericom Semiconductor’s PI3B series of logic circuits are produced
using the Company’s advanced sub micron CMOS technology,
achieving industry leading performance.
The PI3B33X257 is a 3.3V, 24:12 multiplexer/demultiplexer with
three-state outputs. Inputs can be connected to outputs with low
on resistance (5 Ohm) with no additional ground bounce noise or
propagation delay.

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.
