DESCRIPTION:
The QS32253 is a high-speed CMOS TTL-compatible dual 4:1 multi-
plexer/demultiplexer with 3-state outputs. The QS32253 is function and
pinout compatible version of the 74F253, 74FCT253, and the 74ALS/AS/
LS253 dual 4:1 multiplexers. The QS32253 has 25Ω resistors to reduce
ground bounce noise.
Mux/Demux devices provide an order of magnitude faster speed than
equivalent logic devices.
The QS32253 is characterized for operation at -40°C to +85°C.
