Product Description
Pericom Semiconductors PI2B series of logic circuits are produced
using the Companys advanced submicron CMOS technology,
achieving industry leading performance.
The PI2B4300 is a 4-bit, 3-port bus exchange switch designed with
a low ON resistance (5-ohms) allowing inputs to be connected
directly to outputs. The bus switch creates no additional propagational
delay or additional ground bounce noise. The switches are turned
OFF by S

= 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.

Notes:
1. See test circuit and waveforms.
2. This parameter is guaranteed but not tested on Propagation Delays.
3. The bus switch contributes no propagational delay other than the RC delay of the ON resistance of the switch and the load
capacitance. The time constant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much smaller
than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the
bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interaction with the
load on the driven side.
