DESCRIPTION
ABSOLUTE MAXIMUM RATINGS
Input Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . 40V
Output Current (Source or Sink)
The UC1711 family of FET drivers are made with an
all-NPN Schottky process in order to optimize switching
speed, temperature stability, and radiation resistance.
The cost for these benefits is a quiescent supply current
which varies with both output state and supply voltage.
For lower power requirements, refer to the the UC1709
family which is both pin compatible with, and functionally
equivalent to the UC1711.

Note 1: Unless otherwise indicated, voltages are reference to
ground and currents are positive into, negative out of, the spec-
ified terminals. All reliability information for this device has been
gathered at an ambient air temperature of 125°C, and a supply
voltage of 25V.
These devices implement inverting logic with TTL com-
patible inputs, and output stages which will either source,
or sink in excess of 1.5A of load current with minimal
cross-conduction charge. Due to their monolithic con-
struction, the channels are well matched and can be par-
alleled for doubled output current capability.
Note 2: Consult Unitrode databook for information regarding
thermal specifications and limitations of packages.
