(1) The lowest supply voltage at which RESET becomes active. tr, VDD ≥ 15 μs/V.
(2) To ensure best stability of the threshold voltage, a bypass capacitor (ceramic, 0.1 μF) should be placed near the supply terminals.
(3) The RESET short-circuit current is the maximum pullup current when RESET is driven low by a microprocessor bidirectional reset pin.
