PI5C32X245

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.
