Transitions
D Temperature-pensated Threshold
Levels
D High Noise Immunity 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 pensated and can be triggered from the slowest of input ramps and still give clean jitter-free output signals.
