Pin Description
Pin Configuration
Description:
Pericom Semiconductor’s PI5C16245 is a 16-bit, 2-port bus switch
that is 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 switch creates no additional propagation
delay or additional ground bounce noise.
