Note 1
For operating at elevated temperatures the device must be derated based on a a150 C maximum junction temperature and a thermal resistance of
70 CW (Ceramic) 77 CW (Plastic DIP) and 110 CW (SO-14 Narrow)
Note 2
Supply current when output high typically 1 mA less at VCC e 5V
Note 3
Tested at VCC e 5V and VCC e 15V
Note 4
As reset voltage lowers timing is inhibited and then the output goes low
Note 5
This will determine the maximum value of RA a RB for 15V operation The maximum total (RA a RB)is20MX
Note 6
No protection against excessive pin 1 13 current is necessary providing the package dissipation rating will not be exceeded
Note 7
Matching characteristics refer to the difference between performance characteristics of each timer section
Note 8
Refer to RETS556X drawing for specifications of military LM556J version
