Minidip and Power Packages DESCRIPTION
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 -55В°C to 125В°C operation. The UC3705 is
specified for a temperature range of 0В°C to 70В°C and is available in either a plastic minidip or a 5-pin, power
TO-220 package. TRUTH TABLE (1) (2) (1)
