The UC1705 family of power drivers is made with a high sppeed Schottky process to interface between low-level control functions and high-power switching devices - particularly power MOSFETs. These devices are also an optimum choise for capacitive line drivers where up to 1.5 A 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.

Supply voltages for both VS and VC can independently range from 5 V to 40 V. For additional application details, see the UC1707/3707 data sheet (SLUS177).

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.
