Product Description
Pericom Semiconductor’s PI3B series of logic circuits are produced
in the company’s advanced submicron CMOS technology.
The PI3B34X245 is a 3.3V, 32-bit, 2-port bus switch. Four enable
signals (BEn) turn the switches on. The bus switch creates no
additional propagational delay or additional ground bounce noise.

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. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
4. Measured by the voltage drop between A and B pin at indicated current through the switch. ON resistance is determined by
the lower of the voltages on the two (A,B) pins.
5. This parameter is determined by device characterization but is not production tested.
