1.5A Source/Sink Drive
The UC1705 family of power drivers is made with a high speed Schottky pro-
cess 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 ei-
ther direction. With both Inverting and Non-Inverting inputs available, logic sig-
nals of either polarity may be accepted, or one input can be used to gate or
strobe the other.

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

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.
