ISL59446
500MHz Triple 4:1 Gain-of-2, Multiplexing
Amplifier
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.

NOTES:
1. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special
Pb-free material sets, molding compounds/die attach materials, and
100% matte tin plate plus anneal (e3 termination finish, which is
RoHS compliant and compatible with both SnPb and Pb-free
soldering operations). Intersil Pb-free products are MSL classified at
Pb-free peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J STD-020.
3. For Moisture Sensitivity Level (MSL), please see device information
page for ISL59446. For more information on MSL please see tech
brief TB363.
