Notes:

4. To ensure best stability of the threshold voltage, a bypass capacitor (ceramic, 0.1

μF) should be placed near the supply terminals.

5. The

RESET short-circuit current is the maximum pull-up current when RESET is driven low by a P bidirectional reset pin.

6. Test condition for SOT25 and SOT26: Devices mounted on FR-4 substrate PC board, 2oz copper, with minimum recommended pad layout.
