General Description
The EL4142C, EL4342C, EL4144C, and EL4344C are 600MHz
bandwidth multiplexing amplifiers designed primarily for input video
switching. The EL4142C and EL4342C contain 2:1 multiplexers
whereas the EL4144C and EL4344C contain 4:1 multiplexing ampli-
fers. The EL4142C and EL4144C have one channel per package and
three channel versions can be found in the EL4342C and EL4344C.
The gain of the MUX amp is nominally set to 1. 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 referenced to the GND
pin.
The EL4142C is available in the 8-pin MSOP package, the EL4144C
in a 16-pin QSOP, the EL4342C in a 24-pin QSOP, and the EL4344C
in a 28-pin QSOP. All parts are specified for operation over the full
--
-40°C to +85°C temperature range.
