PI5C3384 PI5C3384C 10-Bit, 2-Port Bus Switch Features: Description: Near-Zero propagation delay Pericom Semiconductors PI5C3384 and PI5C3384C are 10-bit, 2-port bus switches designed with a low On-Resistance allowing 5 switches connect inputs to outputs inputs to be connected directly to outputs. The bus switch creates Direct bus connection when switches are ON no additional propagational delay or additional ground bounce Ultra-low quiescent power (0.2A typical) noise. The switches are turned ON by the Bus Enable (BEx) input Ideally suited for notebook applications signals. Two bus enable signals are provided, one for each of the Packaging (Pb-free & Green Available): upper and lower ve bits of the two 10-bit buses. 24-pin 150-mil wide plastic QSOP (Q) 24-pin 300-mil wide plastic SOIC (S) 24-pin 173-mil wide plastic TSSOP (L) Block Diagram Pin Con guration A B 0 0 BE 1 24 V A CC A B 4 4 B 2 23 B 0 9 A 3 22 A 0 9 A 4 21 A 1 8 B 5 20 B 1 8 B 6 19 B 2 7 A B 5 5 A 7 18 A 2 7 A 8 17 A 3 6 B 9 16 B 3 6 A B 9 9 B 10 15 B 4 5 A 11 14 A 4 5 GND 12 13 BE B BE A BE B (1) Truth Table Pin Description Pin Name Description Function BE BE B -B B -B A B 0 4 5 9 BE , BE Bus Enable Inputs (Active LOW) Disconnect H H Hi-Z Hi-Z A B A -A Bus A Connect L H A -A Hi-Z 0 9 0 4 B -A Bus B Connect H L Hi-Z A A 0 9 5- 9 GND Ground Connect L L A -A A -A 0 4 5 9 V Power CC Note: 1.
