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
CC
= 5V.
Note 4:
Tested at V
CC
= 5V and V
CC
= 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
A
+ R
B
for 15V operation. The maximum total (R
A
+ R
B
) 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.
