Product Description:
Pericom Semiconductor’s PI5C series of logic circuits are pro-
duced in the Company’s advanced 0.8 micron CMOS technology,
achieving industry leading performance.
The PI5C34X383 and PI5C34X2383 are 32-bit bus switches with
exchange designed with a low ON resistance allowing inputs to be
connected directly to outputs. The bus switch creates no additional
propagational delay or additional ground bounce noise. The switches
are turned ON by the Bus Enable (BE) input signal, and the Bus
Exchange (BX) input signal offers nibble swapping of the AB and
CD pairs of signals. This exchange configuration allows byte
swapping of buses in systems. It can also be used as a quad
2-to-1 multiplexer and to create low delay barrel shifters, etc. The
PI5C34X2383 is designed with an internal 25
resistor reducing
noise reflection in high-speed applications.
Applications:
16-wide 2:1 MUX, Byte Swapping, and Hot Insertion.
