AC ELECTRICAL CHARACTERISTICS (continued)
(V
CC
= 18V to 36V, V
L
= 2.3V to 5.5V, V
GND
= 0V; all logic inputs at V
L
or GND; T
A
= -40NC to +85NC, unless otherwise noted. Typical
values are at V
CC
= 24V, V
L
= 3.3V, and T
A
= +25NC, unless otherwise noted.) (Note 2)
Note 2: All devices are 100% production tested at T
A
= +25NC. Limits over the operating temperature range are guaranteed by
design.
Note 3: UV is an open-drain output. Connect UV to a voltage less than 5.5V through an external pullup resistor.
Note 4: Disable time measurements are load dependent.
