The IDTQS34XS257 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 bidirectional with a typical 250ps propagation delay through the switch. Clock Enable, overriding Asynchronous Enable, and Asynchronous Select controls provide additional design flexibility.
Synchronous controls ease timing constraints in many high speed data mux/demux applications, such as bank interleaving. The IDTQS34XS257 is available in the space-saving, 80-pin dual-in-line MillipaQ package.
The IDTQS34XS257 is characterized for operation at -40°C to +85°C.
