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, except for through-hole packages, which use a trace
length of zero.
