Product Description
Pericom Semiconductors PI3B series of logic circuits are produced
using the company's advanced submicron CMOS technology.
The PI3B16232 is a 3.3 volt, 16-bit to 32-bit synchronous switch.
Two select inputs (S0 and S1) control the data flow. A clock (CLK)
and a clock enable (CLKEN) synchronize the device operation.
When CLKEN is high, the bus switch remains in the last clocked
function.
