DESCRIPTION:

The QS33X253 is a high-speed CMOS 24:6 (3, dual 4:1) multiplexer/demultiplexer. The QS33X253 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.

FEATURES:

− Enhanced N channel FET with no inherent diode to Vcc

− Bidirectional switches connect inputs to outputs

− 24:6 Mux/Demux switches

− Zero propagation delay, zero ground bounce

− Individual controls for each bank

− Undershoot clamp diodes on all switch and control pins

− TTL-compatible control inputs

− Available in 48-pin QVSOP Package

APPLICATIONS

− Logic replacment

− Video, audio, graphics switching, muxing

− Hot-swapping, hot-docking

− Voltage translation (5V to 3.3V)
