PI5C32X245 16-Bit, 2-Port BusSwitch Features: Description: Near-Zero propagation delay Pericom Semiconductors PI5C32X245 is a 16-bit, 2-port bus switch. Two enable signals (BEn) turn the switches on. The bus 5 switches connect inputs to outputs switch creates no additional propagational delay or additional Direct bus connection when switches are ON ground bounce noise. Ultra-low quiescent power (0.2A typical) Ideally suited for notebook applications Industrial operating temperature: 40C to +85C Packaging (Pb-free & Green available): 40-pin 150-mil wide plastic BQSOP (B) Pin Con guration NC 1 40 VCC Block Diagram A0 2 39 BE1 A1 3 38 B0 A2 4 37 B1 A0 B0 A3 5 36 B2 A4 B3 6 35 A5 A7 B7 B4 7 34 A6 B5 8 33 A7 B6 9 32 BE1 B7 GND 10 31 NC VCC 11 30 A8 B8 A8 BE2 12 29 A9 13 28 B8 A10 14 27 B9 A15 B15 A11 15 26 B10 A12 16 25 B11 BE2 A13 17 24 B12 A14 B13 18 23 A15 B14 19 22 GND 20 21 B15 (1) Truth Table Function BEn A015 Disconnect H Hi-Z Pin Description Connect L B015 Pin Name I/O Description Note: BEn I Bus Enable Input (Active LOW) 1.
