IDTQS3162233
DESCRIPTION:
The QS3162233 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 simultaniously.
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. The QS3162233 adds an internal 25鈩?series
termination resistor to each switch to reduce reflection noise in high-speed
applications.
Mux/Demux devices provide an order of magnitude faster speed than
equivalent logic devices.
The QS3162233 is characterized for operation at -40擄C to +85擄C.
