PI5C16245

PI5C16245 16-Bit, 2-Port Bus Switch Features ÎÎNear-Zero propagation delay ÎÎ5-ohm switches connect inputs to outputs ÎÎDirect bus connection when switches are ON ÎÎUltra-low quiescent power (0.2 μA typical) – Ideally suited for notebook applications ÎÎPin compatible with 74 series16245 ÎÎIndustrial operating temperature: -40°C to +85°C ÎÎPackaging (Pb-free & Green): àà 48-pin 240-mil wide thin plastic TSSOP (A) Block Diagram Description Pericom Semiconductor’s PI5C16245 is a 16-bit, 2-port bus switch that is pin compatible with the 74 series 16245 16-bit transceiver. Two enable signals (nBE) turn the switches on similar to the enable signals of the 16245. The bus switch creates no additional propagation delay or additional ground bounce noise.
