RECOMMENDED OPERATING CONDITIONS FOR RELIABLE OPERATION WITH MARGIN

4.75V ≤ VCCL ≤ 7.5V, -0.3V ≤ VOSEN-x ≤ 0.3V, 0

ELECTRICAL CHARACTERISTICS

The electrical characteristics involve the spread of values guaranteed within the recommended operating

conditions (unless otherwise specified). Typical values represent the median values, which are related to 25°C.
