Output current ±50 mA Description The LMH family of products is joined by the LMH6584 and the LMH6585 high speed, non-blocking, analog, crosspoint switches. The LMH6584/LMH6585 are designed for high speed, DC coupled, analog signals such as high resolution video (UXGA and higher). The LMH6584/LMH6585 have 32 inputs and 16 outputs. The non-blocking architecture allows an output to be connected to any input, including an input that is already selected. With fully buffered inputs the LMH6584/LMH6585 can be impedance matched to nearly any source impedance. The buffered outputs of the LMH6584/LMH6585 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 32 x 32 or 64 x 16 by combining two devices. The LMH6584/LMH6585 are controlled with a 4 pin serial interface. Both single serial mode and addressed chain modes are available. The LMH6584/LMH6585 come in 144-pin LQFP packages. They also have diagonally symmetrical pin assignments to facilitate double sided board layouts and easy pin connections for expansion. Applications Studio monitoring/production video systems Conference room multimedia video systems KVM (keyboard video mouse) systems Security/surveillance systems Multi antenna diversity radio Video test equipment Medical imaging Wide-band routers & switches

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.
