Product Description:
Pericom Semiconductor聮s PI5C series of logic circuits are pro-duced
in the Company聮s advanced submicron CMOS technology.
The PI5C32X2245 is a 16-bit, 2-port bus switch . Two enable signals
(BEn) turn the switches on. The bus switch creates no additional
propagational delay or additional ground bounce noise. The device
has a built-in 25ohm resistor to reduce noise resulting from
reflections, thus eliminating the need for an external terminating
resistor.
