The HFA5250 is the ideal monolithic pin driver solution for highperformance test systems. The device will switch at high datarates between two input voltage levels providing variable amplitudepulses. The output impedance is trimmed to achieve a precision50Ω source for impedance matching. Two differentialECL/TTL compatible inputs control the operation of theHFA5250, one controlling the VHIGH/VLOW switching and theother controlling the output’s high-impedance state. TheHFA5250’s 500MHz data rate makes it compatible with today’shigh speed VLSI test systems and the +7V to -2V output swingallows testing of all common logic families.The HFA5250 is manufactured in the Intersil proprietary complementarybipolar process.
