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 +150C maximum junction temperature and a thermal resistance of 77C/W
(Plastic Dip), and 110C/W (SO-14 Narrow).
Note 3: Supply current when output high typically 1mA less at VCC =5V.
Note 4: Tested at VCC = 5V and VCC = 15V.
Note 5: As reset voltage lowers, timing is inhibited and then the output goes low.
Note 6: This will determine the maximum value of RA +RB for 15V operation. The maximum total (RA +RB)is20M.
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.
