FN7421.3
500MHz Triple, Multiplexing Amplifiers
Features
The EL4340, EL4342 are fixed unity gain mux amps
featuring high slew rates and excellent bandwidth for video
switching. These devices feature a high impedance output
state (HIZ) that enables the outputs of multiple devices to be
wired together. A power-down mode (ENABLE) is included
to turn off un-needed circuitry in power sensitive
applications. The ENABLE pin, when pulled high, sets the
EL4340, EL4342 into standby power mode - consuming just
18mW. An added feature in the EL4340 is a latch enable
function (LE) that allows independent logic control using a
common logic bus.
• Triple 2:1 and 4:1 multiplexers for RGB
• Internally set gain-of-1
• High speed three-state outputs (HIZ)
• Power-down mode (ENABLE)
• Latch enable (EL4340)
• ±5V operation
• ±870 V/µs slew rate
• 500MHz bandwidth
• Typical supply currents 10mA/ch (EL4340) and 15.3mA/ch
(EL4342)
