Supply Voltage 7V Input Voltage 7V Operating Free Air Temperature Range DM54LS b55§Ct o a125§C DM74LS 0 §Ct o a70§C Storage Temperature Range b65§Ct o a150§C Note: The ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaran- teed. The device should not be operated at these limits. The parametric values defined in the ‘‘Electrical Characteristics’’ table are not guaranteed at the absolute maximum ratings. The ‘‘Recommended Operating Conditions’’ table will define the conditions for actual device operation.
