General Description
The LMH family of products is joined by the LMH6580 and the LMH6581, high speed, non-blocking, analog, crosspoint switches. The LMH6580/LMH6581
are designed for high speed, DC coupled, analog signals such as high resolution video (UXGA and higher). The LMH6580/LMH6581
each has eight inputs and four outputs. The non-blocking architecture allows any output to be connected to any input, including
an input that is already selected. With fully buffered inputs the LMH6580/LMH6581 can be impedance matched to nearly any source
impedance. The buffered outputs of the LMH6580/LMH6581 can drive up to two back terminated video loads (75Ω load). The outputs
and inputs also feature high impedance inactive states allowing high performance input and output expansion for array sizes
such as 8 x 8 or 16 x 4 by combining two devices. The LMH6580/LMH6581 are controlled with a 4 pin serial interface that can
be configured as a 3 wire interface. Both serial mode and addressed modes are available.
The LMH6580/LMH6581 come in 48-pin TQFP packages. They also have diagonally symmetrical pin assignments to facilitate double
sided board layouts and easy pin connections for expansion.

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.
