Pin Description
Pin Configuration
Description
Pericom Semiconductor’s PI5C3245 is a 8-bit, 2-port bus switch
designed with a low On-Resistance (5-ohm) 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. The pinout is
compatible with PI74FCT245T (Octal Bidirectional Transceiver).
