03/99
Dual Ultra High-Speed FET Driver
FEATURES
25ns Rise and Fall into 1000pF
15ns Propagation Delay
1.5A Source or Sink Output Drive
Operation with 5V to 35V Supply
High-Speed Schottky NPN Process
8-PIN MINIDIP Package
DESCRIPTION
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.
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
struction, the channels are well matched and can be par-
alleled for doubled output current capability.
