NOTES:
1. All voltages referenced to ground.
2. Measured with outputs open and ST and PBRST within 0.5V of supply rails.
3. PBRST is internally pulled up to V
CC
with an internal impedance of 40K typical.
4. t

5. RST is an open drain output.
6. Must not exceed t

minimum. See Table 1.
7. RST remains within 0.5V of V
CC
on power–down until V
CC
drops below 2.0V. RST remains within 0.5V of
GND on power–down until V
CC
drops below 2.0V.
8. Measured with outputs open and ST and PBRST at TTL levels.
9. Watchdog can not be disabled. It must be strobed to avoid resets.
