Electrical Characteristics
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Note 2: For operating at elevated temperatures the device must be derated based on a +150˚C maximum junction temperature and a thermal resistance of 77˚C/W
(Plastic Dip), and 110˚C/W (SO-14 Narrow).
Note 3: Supply current when output high typically 1mA less at V
Note 4: Tested at V
Note 5: As reset voltage lowers, timing is inhibited and then the output goes low.
Note 6: This will determine the maximum value of R
Note 7: No protection against excessive pin 1, 13 current is necessary providing the package dissipation rating will not be exceeded.
Note 8: Matching characteristics refer to the difference between performance characteristics of each timer section.
Note 9: Refer to RETS556X drawing of military LM556J versions.
