Description

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.

The ISL59446 (4:1) and ISL59448 (2:1) are fixed gain of 2 mux amps featuring high slew rates and excellent bandwidth for video switching. These devices feature a three-state output (HIZ) that enables the outputs of multiple devices to be wired together. A power-down mode (ENABLE) is included to turn off un-needed circuitry in power sensitive applications. The ENABLE pin, when pulled high, sets the ISL59446 and ISL59448 into standby power mode - consuming just 18mW. An added feature in the ISL59448 is a latch enable function (LE) that allows independent logic control using a common logic bus.
