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

= 5V.

Note 4: Tested at V

= 5V and V

= 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 R + R for 15V operation. The maximum total (R + R ) is 20 MΩ.

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.
