NOTES:

1.

All voltages referenced to ground.

2.

Measured with outputs open and

and

within 0.5V of supply rails.

3.

is internally pulled up to Vcc with an internal impedance of 40k typical.

4.

5.

is an open-drain output.

6.

7.

RST remains within 0.5V of Vcc on power-down until Vcc drops below 2.0V.

remains within 0.5V of GND on power-down until

Vcc drops below 2.0V.

8.

Measured with outputs open and

and

at TTL levels.

9.

Watchdog can not be disabled. It must be strobed to avoid resets.
