Notes:
1. Production testing done at T
A
= 25°C. Over temperature specifications guaranteed by design only using six sigma design limits.
2. R
S
E output is active LOW for the IMP811 and RESET output is active HIGH for the IMP812.
E T
3. Glitches of 100ns or less typically will not generate a reset pulse.
