HEX SCHMITT-TRIGGER INVERTERS
SCAS285X MARCH 1993 REVISED JULY 2005
The devices contain six independent inverters and perform the Boolean function Y = A.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators
in a mixed 3.3-V/5-V system environment.

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.
(2)
The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed.
