QS33X257 - Block Diagram
Description
The QS33X257 is a high-speed CMOS TTL-compatible 24:12 multiplexer/demultiplexer. The QS33X257 is functionally compatible to three of the QuickSwitch versions 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. The QS33X257 operates at -40 °C to +85 °C.
Applications
- Logic replacement
- Video, audio, graphics switching, muxing
- Hot-swapping, hot-docking
- Voltage translation (5V to 3.3V)
- Bus funneling
