DESCRIPTION
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.
Supply voltages for both V
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.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
