DESCRIPTION:
The QS3253 is a high-speed CMOS TTL-compatible dual 4:1 multi-
plexer/demultiplexer with 3-state outputs. The QS3253 is function and
pinout compatible version of the 74F253, 74FCT253, and the 74ALS/AS/
LS253 dual 4:1 multiplexers. The low ON resistance of the QS3253 allows
inputs to be connected to outputs without adding propagation delay and
without generating additional ground bounce noise.
Mux/Demux devices provide an order of magnitude faster speed than
equivalent logic devices.
The QS3253 is characterized for operation at -40°C to +85°C.
