description
Each circuit functions as a 4-input NAND gate, but because of the Schmitt action, it has different input threshold levels for positive-going (VT+) and negative-going (VT–) signals. The 74AC11013 is characterized for operation from – 40°C to 85°C.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
