pF
Typical values apply at TA = 25°C.
The lowest supply voltage at which RESET becomes active. The symbol Vres is not currently listed within EIA or JEDEC standards for
semiconductor symbology. Rise time of VDD ≥ 15 s/V.
NOTES:
2. All characteristics are measured with CT = 0.1 F.
3. To ensure best stability of the threshold voltage, a bypass capacitor (ceramic, 0.1
F) should be placed near the supply terminals.
