Note 1: Limiting input current to 100µA 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.

3: See “Output Clamp” under detailed description.
