The QS3383 provides ten high-speed CMOS TTL-compatible bus
switches. The low ON resistance of the QS3383 allows inputs to be
connected to outputs without adding propagation delay and without gener-
ating 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 QS3383 is characterized for operation at -40擄C to +85擄C.
