Features
Near-Zero propagation delay
5-ohm switches connect inputs to outputs
Direct bus connection when switches are on
Ultra Low Quiescent Power (0.2μA typical)
– Ideally suited for notebook applications
Pin compatible with 74 series 245 logic devices
Packaging (Pb-free & Green available):
– 20-pin 173-mil wide plastic TSSOP (L)
– 20-pin 150-mil wide plastic QSOP (Q)
– 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).
