Product Description
Pericom Semiconductor聮s PI2B series of logic circuits are produced
using the Company聮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 S
0
= H and S
1
= H. The
A bus can be connected to B bus by S
0
= L and S
1
= L. The B bus
can be connected to C bus by S
0
= H and S
1
= L. The C bus can be
connected to A bus by S
