Pericom Semiconductor’s PI2B series of logic circuits are produced
using the Company’s 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 S0 = H and S1 = H. The
A bus can be connected to B bus by S0 = L and S1 = L. The B bus
can be connected to C bus by S0 = H and S1 = L. The C bus can be
connected to A bus by S0 = L and S1 = H.

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 = 2.5V, TA = 25°C 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.

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.

Notes:
1. CL includes probe and jig capacitance.
2. Waveform 1 is for an output with internal conditions such that the output is LOW except when disabled by the output control.
Waveform 2 is for an output with internal conditions such that the output is HIGH except when disabled by the output control.
3. All input pulses are supplied by generators having the following characteristics: PRR<10MHz, ZO = 50 ohms, tR ≤ 2ns, tF ≤ 2ns.
4. The outputs are measured one at a time with one transition per measurement.
5. tPLZ and tPHZ are the same as tDIS.
6. tPZL and tPZH are the same as tEN.
7. tPLH and tPHL are the same as tPD.
