APPLICATIONS INFORMATION
maintain micropower operation, the output stage uses a
break-before-make circuit. The break interval of this circuit
turns off both the pull-up and pull-down devices for tens
of nanoseconds before activating the appropriate output
transistor (depends on the output transition direction).
Any load connected to the output will charge or discharge
internal capacitance during this interval. This can create a
soft corner during output transitions and also decrease the
propagation delay. The Typical Performance Characteristics
section shows this behavior under three load conditions:
unloaded, 10k to ground and 200Ω to ground. Loads to
V+ have a similar affect when the output is transitioning
from low to high.
Power Supplies
The comparator circuitry operates from a single 1.7V
to 5.5V. A 0.1μF minimum bypass capacitor is required
between the V+ pin and GND. When the output is sinking
at least 1mA, a 1μF bypass capacitor is recommended.
Pulsing the V+ supply to the comparators on and off may
engage the ESD protection circuitry at the V+ pin. If this
occurs, current is pulled from the V+ pin through the output
stage. Using the recommended supply bypass capacitors
with some series resistance in the V+ supply line will help
to prevent this action in pulsed supply applications.
Level Translators
The level translators in the Typical Applications section
show an adjustable high-precision voltage reference
enabling the user to vary the threshold voltage. Simply
adjusting the ratio of the two resistors changes the thresh-
old voltage according to the following equation:
VTHR = 0.4 1+
