Direct bus connection when switches are ON
Ultra Low Quiescent Power (0.2 碌A(chǔ) Typical)
鈥?Ideally suited for notebook applications
Product Description:
Pericom Semiconductor鈥檚 PI5C series of logic circuits are pro-
duced in the Company鈥檚 advanced 0.8 micron CMOS technology,
achieving industry leading speed grades.
The PI5C3400 is a 4-bit, 4-port bus switch with individual exchanges
designed with a low ON resistance (5鈩? allowing inputs to be
connected directly to outputs. The bus switch creates no additional
propagational delay or ground bounce noise. The switches are
turned ON by the Bus Enable (BE) input signal, and the Bus
Exchange (BX

) input signals offer individual bit swapping
of the AB and CD signal pairs. This exchange configuration allows
bit swapping of buses in systems.
