description
The 74ACT11014 contains six independent inverters. The device performs the Boolean function Y = A. Because of the Schmitt action, the device has different input threshold levels for positive-going (VT+) and negative-going (VT) signals. The 74ACT11014 is temperature compensated and can be triggered from the slowest of input ramps and still give clean, jitter-free output signals. It also has a greater noise margin than conventional inverters. The 74ACT11014 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 negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
