Hysteresis voltage between Schmitt trigger switching levels. Based on characterization results, not tested. 2. The IIO current sunk must always respect the absolute maximum rating specified in Section 13.2 and the sum of IIO (I/O ports and control pins) must not exceed IVSS. 3. The RON pull-up equivalent resistor is based on a resistive transistor. This data is based on characterization results, not tested in production. 4. To guarantee the reset of the device, a minimum pulse has to be applied to RESET pin. All short pulses applied on RESET pin with a duration below th(RSTL)in can be ignored. |
