10-Bit Low Power Bus-Exchange Switch
FST3383 10-Bit Low Power Bus Exchange Switch December 1993 Revised December 2000 FST3383 10-Bit Low Power Bus Exchange Switch General Description Features The FST3383 provides two sets of high-speed CMOS TTL-5Ω switch connection between two ports compatible bus switches. The low on resistance of theZero propagation delay switch allows inputs to be connected to outputs without Ultra low power with 0.2 μA typical I CC adding propagation delay or generating additional ground Zero ground bounce in flow-through mode bounce noise. The device operates as a 10-bit bus switch or a 5-bit bus exchanger. The bus exchange (BX) signalControl inputs compatible with TTL level provides nibble swapping of the AB and CD pairs of sig- nals. 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. The bus enable (OE) signal turns the switches ON.
