Notes: 1. Symbol “•” denotes specification applies over -40 to +125 ° C.
2. This parameter is guaranteed by design and/or laboratory characterization.
3. Guaranteed within the output limits of (V+ – 0.2 V) to (V- + 0.2 V).
4. Specifies the worst case drive voltage relative to the supply rail under stated load conditions.
