Notes:

1. Production testing done at TA = 25°C. Over-temperature specifications guaranteed by design only using six sigma design limits.

2. RESET output is active LOW for the ASM811 and RESET output is active HIGH for the ASM812.

3. Glitches of 100ns or less typically will not generate a reset pulse.
