DESCRIPTION:
The QS34XS257 is a high-speed CMOS quad 32:16 multiplexer/
demultiplexer. It is organized as four independent quad 2:1 mux/demux
blocks. Port selection and connection, controlled by SEL signals, can be
either asynchronous or synchronous. In the synchronous mode, the A or
B port to Y port connection is updated on the rising edge of the input clock
CLK. Once the port-to-port connection is made, data flow can be bi-
directional with a typical 250ps propagation delay through the switch. Clock
Enable, overriding Asynchronous Enable, and Asynchronous Select con-
trols provide additional design flexibility.
Synchronous controls ease timng constraints in many high speed data
mux/demux applications, such as bank interleaving. The QS34XS257 is
available in the space-saving, 80-pin dual-in-line MillipaQ package.
The QS34XS257 is characterized for operation at -40°C to +85°C.
