Pericom Semiconductor PI5C3383
The PI5C3383 is a 5-bit, 4-port bus switch with exchange designed with a low On-Resistance allowing inputs to be connected directly to outputs. The switch creates no additional propagational delay or additional ground bounce noise. The switch is turned ON by the Bus Enable (BE) input signal, and the Bus Exchange (BX) input signal offers nibble swapping of the AB and CD pairs of signals.FEATURES
● Near-Zero propagation delay● 5Ω switches connect inputs to outputs
● Direct bus connection when switches are ON
● Ultra-low quiescent power (0.2µA typical) – Ideally suited for notebook applications
● Packaging (Pb-free & Green available): – 24-pin 173-mil wide plastic TSSOP (L) – 24-pin 150-mil wide plastic QSOP (Q) – 24-pin 300-mil wide plastic SOIC (S)
DESCRIPTION
This exchange configuration allows byte swapping of buses in systems. It can also be used as a quad 2-to-1 multiplexer and to create low delay barrel shifters, etc. Block Diagram A0 C0 Pin Configuration BE C0 A0 B0 D0 C1 A1 B1 D1 C2 A2 GND 1 2 3 4 5 6 7 8 9 10 11 12 24 23 22 21 20 19 18 17 16 15 14 13 B0 D0 A4 C4 Vcc D4 B4 A4 C4 D3 B3 A3 C3 D2 B2 BX B4 D4 BX BE PinDESCRIPTION
