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 allowing inputs to be connected directly to
outputs. The switches are turned OFF by S

Note:
Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the de-
vice. This is a stress rating only and functional
operation of the device at these or any other condi-
tions above those indicated in the operational sec-
tions of this specification is not implied. Exposure to
absolute maximum rating conditions for extended
periods may affect reliability.
Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at V
CC
= 2.5V, T
A
= 25C ambient and maximum loading.
3. 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.
4. This parameter is determined by device characterization but is not production tested.
Maximum Ratings
(Above which the useful life may be impaired. For user guidelines, not tested.)

Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.
2. Typical values are at V
CC
= 2.5V, +25C ambient.
Notes:
1. See test circuit and waveforms.
2. This parameter is guaranteed but not tested on Propagation Delays.
3. The bus switch contributes little 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 1.0ns for 30pF load. Propagation 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.
