ELECTRICAL CHARACTERISTICS (continued)

(V

CC

= 2.8V to 14V, T

A

= T

J

= -40NC to +85NC, unless otherwise specified. Typical values are at V

ABP

= V

DBP

= V

CC

= 3.3V,

T

A

= +25NC.) (Note 2)

Note 2: Specifications are guaranteed for the stated global conditions, unless otherwise noted. 100% production tested at T

A

=

+25NC and T

A

= +85NC. Specifications at T

A

= -40NC are guaranteed by design.

Note 3: For V

CC

of 3.6V or lower, connect V

CC

, DBP, and ABP together. For higher supply applications, connect only V

CC

to the

supply rail.

Note 4: Applies to RESET (except for a reset timeout period of 25Fs), fault, autoretry, sequence delays, and watchdog timeout.
