(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.
(3) For operating at elevated temperatures the device must be derated above 25°C based on a 150°C maximum junction temperature and a thermal resistance of 106°C/W (PDIP), 170°C/W (S0IC-8), and 204°C/W (VSSOP) junction to ambient.
(4) Refer to RETS555X drawing of military LM555H and LM555J versions for specifications.

(1) All voltages are measured with respect to the ground pin, unless otherwise specified.
(2) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Recommended Operating Conditions indicate conditions for which the device is functional, but do not ensure specific performance limits.
Electrical Characteristics state DC and AC electrical specifications under particular test conditions which ensures specific performance limits. This assumes that the device is within the
Recommended Operating Conditions. Specifications are not ensured for parameters where no limit is given, however, the typical value is a good indication of device performance.
(3) Supply current when output high typically 1 mA less at VCC = 5 V.
(4) Tested at VCC = 5 V and VCC = 15 V.
(5) This will determine the maximum value of RA + RB for 15 V operation. The maximum total (RA + RB) is 20 MΩ.
(6) No protection against excessive pin 7 current is necessary providing the package dissipation rating will not be exceeded.
