Features 500 MHz, 500 mV -3 dB bandwidth, AV = 2 400 MHz, 2VPP -3 dB bandwidth, AV = 2 8 ns channel switching time 70 dB channel to channel isolation @ 10 MHz 0.02%, 0.05° diff. gain, phase 0.1 dB gain flatness to 150 MHz 2200 V/µs slew rate Wide supply voltage range: 6V (±3V) to 12V (±6V) -68 dB HD2 @ 5 MHz -84 dB HD3 @ 5 MHz Description The LMH™6574 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's 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 load. An 80 mA linear output current is available for driving multiple video load applications. The LMH6574 gain is set by external feedback and gain set resistors for maximum flexibility. The LMH6574 is available in the 14 pin SOIC package. Applications Video router Multi input video monitor Instrumentation / Test equipment Receiver IF diversity switch Multi Channel A/D Driver Picture in Picture video switch

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
LMH6574MA	VIP 10	0	13411	0	0	1245000	3	353272149
LMH6574MAX	VIP 10	0	13411	0	0	1245000	3	353272149

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
