10.9 CONTROL PIN CHARACTERISTICS
10.9.1 Asynchronous RESET Pin
Subject to general operating conditions for V
Notes:
1. Unless otherwise specified, typical data are based on T
2. Data based on characterization results, not tested in production.
3. Hysteresis voltage between Schmitt trigger switching levels. Based on characterization results, not tested.
4. The R
5. All short pulse applied on RESET pin with a duration below t
6. The reset network protects the device against parasitic resets, especially in a noisy environment.
7. The output of the external reset circuit must have an open-drain output to drive the ST6 reset pad. Otherwise the device
