UC1705 UC2705 UC3705 High Speed Power Driver FEATURES DESCRIPTION • 1.5A Source/Sink Drive • 100 nsec Delay • 40 nsec Rise and Fall into 1000pF • Inverting and Non-Inverting Inputs The UC1705 family of power drivers is made with a high speed Schottky process to interface between low-level control functions and high-power switching devices - particularly power MOSFETs. These devices are also an optimum choice for capacitive line drivers where up to 1.5 amps may be switched in either direction. With both Inverting and Non-Inverting inputs available, logic signals of either polarity may be accepted, or one input can be used to gate or strobe the other. • Low Cross-Conduction Current Spike • Low Quiescent Current • 5V to 40V Operation • Thermal Shutdown Protection • MINIDIP and Power Packages N.I H H L L The UC1705 is packaged in an 8-pin hermetically sealed CERDIP for -55°C to +125°C operation. The UC3705 is specified for a temperature range of 0°C to +70°C and is available in either a plastic minidip or a 5-pin, power TO-220 package.
