• Description: Dual/triple Ultra-low Voltage Supervisors With Push-button Reset With Delay Option
• Manufacturer: STMicroelectronics

Table 6.
1. Valid for ambient operating temperature: T
2. Input leakage for the MRC pin is not tested.
3. Guaranteed by design.
4. The leakage current measured on the RST pin is tested with the reset de-asserted (output high impedance).
5. Selecting the appropriate external capacitor (preferably less than 100pF) allows systems designers to vary the minimum
