General Description
The EL4342C and EL4346C are 600MHz bandwidth multiplexing
amplifiers designed primarily for input video switching. The
EL4342C and EL4346C contain 2:1 multiplexers.
The EN pin can be used to tri-state the MUX output, enabling parts to
be paralleded for a greater number of inputs. All logic inputs are refer-
enced to the GND pin.
The EL4342C has a gain of 1 and the EL4346C has a gain of 2.
The EL4342C and EL4346C are available in a 24-pin QSOP package
and are specified for operation over the full -40°C to +85°C tempera-
ture range.
