Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when ordering the device

beyond its rated operating conditions.

Note 2: TJ Max = 150˚C for the Molded DIP, and 175˚C for the Ceramic DIP.

Note 3: Ratings apply to ambient temperature at 25˚C. Above this temperature, derate the 16L-Ceramic DIP at 10 mW/˚C, and the 16L-Molded DIP at 8.3 mW/˚C.

Note 4: For supply voltages less than 30V, the absolute maximum voltage is equal to the supply voltage.

Note 5: A military RETS specification is available on request. At the time of printing, the LM78S40 RETS specification complied with the Min and Max limits in this

table. The LM78S40J may also be procured as a Standard Military Drawing.
