Permits Hot Insertion Pin compatible with 74 series16245 Operating Vcc Range: 3.0V to 3.6V Industrial operating temperature: –40°C to +85°C Packages available: – 48-pin 240 mil wide thin plastic TSSOP (A) – 48-pin 300 mil wide plastic SSOP (V) Product Description Pericom Semiconductor’s PI3B series of logic circuits are produced using the Company’s advanced 0.35 micron CMOS technology. The PI3B16245 and PI3B162245 are 3.3 volt, hot-insertion, 16-bit, 2-port bus switches that are 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 switches create no additional propagational delay or additional ground bounce noise. The PI3B162245 device has a built-in 25-ohm series resistor to reduce noise resulting from reflections, thus eliminating the need for an external terminating resistor.
