PI5C3245
8-Bit, 2-Port Bus Switch
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 ad-
ditional 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).
