... Application Information INTRODUCTION The LMH6580/LMH6581 are high speed, fully buffered, non- blocking, analog crosspoint switches. Having fully buffered inputs allows the LMH6580/LMH6581 to accept signals from low or high impedance sources without the worry of loading the signal source. The fully buffered outputs will drive 75Ω or 50Ω ...
