The IDTQS33X257 is a high-speed CMOS TTL-compatible 24:12 multi-plexer/demultiplexer. The IDTQS33X257 is functionally compatible to three of the QuickSwitch version of the 74F257, 74FCT257, and the 74ALS/AS/LS257 Quad 2:1 multiplexers. The low ON resistance of the QS33X257 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. This part will be used in wide bus multiplexing where board space is at a premium.
Mux/Demux devices provide an order of magnitude faster speed than equivalent logic devices.
The IDTQS33X257 is characterized for operation at -40°C to +85°C.
