The QS3L383 provides ten high-speed CMOS TTL-compatible bus switches. The low ON resistance of the QS3L383 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The Bus Enable (BE) signal turns the switches on. The Bus Exchange (BX) signal provides nibble swap of the AB and CD pairs of signals. This exchange configuration allows byte swapping of buses in systems. It can also be used as a 5-wide 2-to-1 multiplexer and to create low delay barrel shifters, etc.
The QS3L383 is characterized for operation at -40°C to +85°C.
