Absolute Maximum Ratings Thermal Information Operating Conditions Temperature Range Thermal Resistance (Typical, Note 1)θJA (oC/W) θJC (oC/W) CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operationo ft h e device at these or any other conditions above those indicated in the operational sections of this specification is not implied. NOTE: 1. θJA is measured with the component mounted on an evaluation PC board in free air.

When the output is in a high state, the DC supply current is typically 1mA less than the low state value. 3. The threshold current will determine the sum of the values of R 1 and R2 to be used in Figure 4 (astable operation); the maximum total R 1 + R2 = 20MΩ . CA555, CA555C, LM555C
