description/ordering information
In these devices, each circuit functions as a quadruple NOR gate. They perform the Boolean function Y = A · B or Y = A + B in positive logic. However, because of the Schmitt action, the inputs have different input threshold levels for positive- and negative-going signals. These circuits are temperature compensated and can be triggered from the slowest of input ramps and still give clean jitter-free output signals.

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. NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 2. The package thermal impedance is calculated in accordance with JESD 51-7.
