Product Description:
Pericom Semiconductor’s PI5C series of logic circuits are pro-
duced in the Company’s advanced 0.6 micron 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 25Ω resistor to reduce noise resulting
from reflections, thus eliminating the need for an external
terminating resistor.
