The IDTQS33X253 is a high-speed CMOS 24:6 (3, dual 4:1) multiplexer/demultiplexer. The IDTQS33X253 is a member of the MultiWidth™ family and is functionally compatible to three of the QuickSwitch version of the 74F253, 74FCT253, and the 74ALS/AS/LS253 Dual 4:1 multiplexers. The low ON resistance of the QS33X253 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. TTL compatible control circuitry with "Break-before-make" feature avoids bus contention on the demux side. This part is ideal for video switching and four way memory bank interleaving applications.
Mux/Demux devices provide an order of magnitude faster speed than equivalent logic devices.
The IDTQS33X253 is characterized for operation at -40 to +85
