EL4344C/EL4348C - Preliminary
600MHz Multiplexing Amplifiers
General Description
The EL4344C and EL4348C are 600MHz bandwidth multiplexing
amplifiers designed primarily for input video switching. The
EL4344C and EL4348C contain 4:1 multiplexing amplifiers.
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 EL4344C has a gain of 1 and the EL4348C has a gain of 2.
The EL4344C and the EL4348C are available in a 28-pin QSOP pack-
age and are specified for operation over the full ---40°C to +85°C
temperature range.
