Product Description
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.
