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.
