NOTES: 1. Limiting input current to 100

µA is recommended to avoid latch-up problems. Typically, 1mA is safe; however, this is not guaranteed.

2. Output clamp not connected. See typical characteristics curves for output swing versus clamp current characteristics.

*Static-sensitive device. Unused devices must be stored in conductive material. Protect devices from static discharge and static fields. Stresses above

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 above those indicated in the operational sections of the specifications is not implied. Exposure to Absolute

Maximum Rating Conditions for extended periods may affect device reliability.
