The LMH6574 is a high-performance analog multiplexer optimized for professional grade
video and other high fidelity high bandwidth analog applications. The output amplifier selects any
one of four buffered input signals based on the state of the two address bits. The LMH6574 provides
a 400-MHz bandwidth at 2 VPP output signal levels. Multimedia and high
definition television (HDTV) applications can benefit from the LMH6574 0.1 dB bandwidth of 150 MHz
and its 2200 V/µs slew rate.
The LMH6574 supports composite video applications with its 0.02% and 0.05° differential
gain and phase errors for NTSC and PAL video signals while driving a single, back terminated 75-Ω
load. An 80-mA linear output current is available for driving multiple video load
The LMH6574 gain is set by external feedback and gain set resistors for maximum
The LMH6574 is available in the 14-pin SOIC package.
