Description

Pericom Semiconductor’s PI5C3245QE is an 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).

Specifications and 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)

Application Scenarios

The PI5C3245QE is suitable for various applications that require signal switches, encoders & decoders, or multiplexers. Its low on-resistance and near-zero propagation delay make it an ideal choice for applications where inputs need to be connected directly to outputs with minimal delay or additional noise.
