unless otherwise noted. On all other products, production
processing does not necessarily include testing of all parameters.
description/ordering information
These Schmitt-trigger devices contain six independent inverters. They perform the Boolean function Y = A.
Because of the Schmitt action, they have different input threshold levels for positive-going (V
T+
) and for
negative-going (V
T−
) signals.
These circuits are temperature compensated and can be triggered from the slowest of input ramps and still give
clean, jitter-free output signals. They also have a greater noise margin than conventional inverters.

† 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.
