资料介绍
The ISL59446 is a triple channel 4:1 multiplexer featuring integrated amplifiers 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.
