CI Input capacitance at MR and CT VI = 0 V to VDD 5 pF
(1) The lowest voltage at which the RESET output 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 terminal.
(3) If manual reset is unused, MR should be connected to VDD to minimize current consumption.
