Product Description
Pericom Semiconductor’s PI3B series of logic circuits are produced
using the Company’s advanced 0.35 micron CMOS technology.
The PI3B16245 and PI3B162245 are 3.3 volt, hot-insertion, 16-bit,
2-port bus switches that are pin compatible with the 74 series 16245
16-bit transceiver. Two enable signals (nBE) turn the switches on
similar to the enable signals of the 16245. The bus switches create
no additional propagational delay or additional ground bounce
noise.
The PI3B162245 device has a built-in 25-ohm series resistor to
reduce noise resulting from reflections, thus eliminating the need
for an external terminating resistor.
