SYNCHROSWITCH
QUAD 2:1 MUX/DEMUX
DESCRIPTION:
TheQS3S257isahigh-speedCMOSQuad2:1 multiplexer/demultiplexer.
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 controls
provide additional design flexibility. Synchronous controls eases timing
constraints in many high speed data mux/demux applications, such as bank
interleaving. The QS3S257 can also be used in 5V to 3.3V translation.
QuickSwitch Mux/Demux devices provide an order of magnitude faster
speed than equivalent logic devices.
The QS3S257 is characterized for operation at -40°C to +85°C.
