TIMING CHARACTERISTICS

(+2.2V ≤ V

≤ +3.6V, +1.62V ≤ V

≤ +3.2V; C

IOVL_

≤ 15pF, C

IOVCC_

≤ 10pF; R

SOURCE

< 150Ω, rise/fall time < 3ns, EN = V

= -40°C to +85°C, unless otherwise noted. Typical values are at V

= +3.3V, V

= +1.8V, and T

= +25°C.) (Notes 1, 2)

Note 1: All units are 100% production tested at T

= +25°C. Limits over the operating temperature range are guaranteed by

correlation and design and not production tested.

Note 2: V

must be less than or equal to V

during normal operation. However, V

can be greater than V

during startup and

shutdown conditions.

Note 3: When V

is below V

by more than the V

- V

shutdown threshold, the device turns off its pullup generators and the I/Os

enter their respective shutdown states.

Note 4: Guaranteed by design.

Note 5: Input thresholds are referenced to the boost circuit.
