Description
The ISL59448 is a triple channel 2:1 multiplexer featuring integrated buffers with a fixed gain of 2, high slew-rate and excellent bandwidth for video switching. The device features a three-state output (HIZ), which allows the outputs of multiple devices to be tied together. A power-down mode (ENABLE) is included to turn off un-needed circuitry in power sensitive applications. When the ENABLE pin is pulled high, the part enters a power-down mode and consumes just 14mW. An additional feature is a latch enable function (LE) that allows independent logic control using a common logic bus.
Applications
- HDTV/DTV analog inputs
- Video projectors
- Computer monitors
- Set-top boxes
- Security video
- Broadcast video equipment
