DESCRIPTION:
The QS3L384 provides a set of ten high-speed CMOS TTL-compatible
bus switches. The low ON resistance of the QS3L384 allows inputs to be
connected to outputs without adding propagation delay and without gener-
ating additional ground bounce noise. The Bus Enable (BE) signals turn the
switches on. Two bus enable signals are provided, one for each of the upper
and lower five bits of the two 10-bit buses.
The QS3L384 is characterized for operation at -40°C to +85°C.
