A product Line of Diodes Incorporated PI3B32X245 3.3V, Hot Insertion 16-Bit, 2-Port Bus Switch Features Description Fast Switching Speed: 4.5ns max. e PTh I3B32X245 is a 3.3V,16-bit, 2-port bus switch. Two enable signals (BEn) turn the switches on. The bus switch creates no Permits Hot Insertion additional propagational delay or additional ground bounce Near-zero propagation delay noise. 5 switches connect inputs to outputs Direct bus connection when switches are ON Ultra-low quiescent power (1.0A typical) Pin Configuration Ideally suited for notebook applications Industrial operating temperature: 40C to +85C NC 1 40 V CC TTL - compatible control of input levels A 2 39 BE 0 1 Packages (Pb-free & Green available): A 3 38 B 1 0 40-pin, 150-mil wide plastic BQSOP (B) A B 2 4 37 1 A 3 B 5 36 2 Logic Block Diagram A 4 6 35 B 3 A B 5 7 34 4 B0 A0 A 6 8 33 B 5 A 7 9 32 B 6 A7 B4 B GND 10 31 7 NC 11 30 V CC A 8 12 29 BE 2 BE1 A 9 13 28 B 8 A 10 14 27 B 9 B8 A A8 11 15 26 B 10 A 16 25 B 12 11 A 13 17 24 B 12 B15 A15 B A 18 23 13 14 A B 15 19 22 14 GND 20 21 B 15 BE2 (1) Truth Table Pin Description Function BEn A0-15 Pin Name I/O Description Disconnect H Hi-Z BEn I Bus Enable Input (Active LOW) Connect L B0-15 A0-A15 I/O Bus A Notes: B0-B15 I/O Bus B 1.
