DESCRIPTION:
compatible bus switches. The low ON resistance of the QS32XL383 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 10-wide 2-to-
1 multiplexer and to create low delay barrel shifters, etc.
PRODUCTS
The QS32XL383 provides two sets of ten high-speed CMOS TTL-
The QS32XL383 is characterized for operation at -40°C to +85°C.
