PI5C16245 16-Bit, 2-Port Bus Switch Features Description Near-Zero propagation delay Pericom Semiconductors PI5C16245 is a 16-bit, 2-port bus switch 5-ohm switches connect inputs to outputs that is pin compatible with the 74 series 16245 16-bit transceiver. Two enable signals (nBE) turn the switches on similar to the en- Direct bus connection when switches are ON able signals of the 16245. e Th bus switch creates no additional Ultra-low quiescent power (0.2 A typical) Ideally suited propagation delay or additional ground bounce noise. for notebook applications Pin compatible with 74 series16245 Industrial operating temperature: -40C to +85C Packaging (Pb-free & Green): 48-pin 240-mil wide thin plastic TSSOP (A) Block Diagram Pin Configuration NC 1 48 1BE 1A0 1B0 1B0 2 47 1A0 1B1 3 46 1A1 GND 4 45 GND 1B2 5 44 1A2 1A7 1B7 1B3 6 43 1A3 VCC 7 42 VCC 1B4 8 41 1A4 1B5 9 40 1A5 1BE GND 10 39 GND 1B6 11 38 1A6 1B7 12 37 1A7 2B0 13 36 2A0 2A0 2B0 2B1 14 35 2A1 GND 15 34 GND 2B2 16 33 2A2 2B3 17 32 2A3 2A7 2B7 VCC 18 31 VCC 2B4 19 30 2A4 2B5 20 29 2A5 2BE GND 21 28 GND 2B6 22 27 2A6 2B7 23 26 2A7 (1) NC 24 25 2BE Truth Table Function nBE nA07 Pin Description Disconnect H Hi-Z Pin Name I/O Description Connect L nB07 nBE I Bus Enable Input (Active LOW) Note: H = High Voltage Level nA0-nA7 I/O Bus A L = Low Voltage Level nB0-nB7 I/O Bus B Hi-Z = High Impedance All trademarks are property of their respective owners. www.pericom.com PS7025F 09/21/10 11-0002 1PI5C16245 16-Bit, 2-Port Bus Switch Absolute Maximum Ratings Parameter Min.
