PI5C32X245
16-Bit, 2-Port BusSwitch
Product Features:
• Near-Zero propagation delay
• 5Ω 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 QS32X245
• Industrial operating temperature: –40°C to +85°C
• Packaging (Pb-free & Green available):
– 40-pin 150-mil wide plastic BQSOP (B)
Description:
Pericom Semiconductor’s PI5C32X245 is a 16-bit, 2-port bus
switch. Two enable signals (BEn) turn the switches on. The bus
switch creates no additional propagational delay or additional
ground bounce noise.
