EL4344C

EL4344C/EL4348C - Preliminary EL4344C/EL4348C - Preliminary 600MHz Multiplexing Amplifiers Features 4:1 Mux Triple channels ±5V operation Gain of 1 (EL4344C) Gain of 2 (EL4348C) 600MHz bandwidth Supply current of 11mA/channel 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 referenced 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 package and are specified for operation over the full ---40°C to +85°C temperature range.
