DESCRIPTION

Normal operational mode for device. If LP is left floating, then a weak internal pullup to VCC

H

Normal mode

pulls it to VCC.

LP

Low-power

Device is forced into a low-power state, causing the inputs and outputs to go to a

L

mode

high-impedance state. All other inputs are ignored.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating

Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
