– 20-pin 300-mil wide plastic SOIC (S)

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

propagationaldelayoradditionalgroundbounce noise.Theswitches

are turned on by the Bus Enable (BE) input signal. The pinout is

compatible with PI74FCT245T (Octal Bidirectional Transceiver).
