The QS316233 is a 32-bit to 16-bit high-speed CMOS, TTL-compatible
switch which can multiplex or demultiplex data. It can be used for memory
interleaving where two memory banks need to be addressed simulta-
neously. It can also be used as two 16-bit to 8-bit multiplexers or as one
32-bit to 16-bit multiplexer. SELn inputs control the data flow. TESTn inputs
control either one or two ports connection.
Mux/Demux devices provide an order of magnitude faster speed than
equivalent logic devices.
The QS316233 is characterized for operation at -40擄C to +85擄C.
