DM54132/DM74132 Quad 2-Input NAND Gates with Schmitt Trigger Inputs June 1989 DM54132/DM74132 Quad 2-Input NAND Gates with Schmitt Trigger Inputs General Description This device contains four independent gates each of which performs the logic NAND function. Each input has hystere- sis which increases the noise immunity and transforms a slowly changing input signal to a fast changing, jitter-free output.

The device should not be operated at these limits. The parametric values defined in the ‘‘Electrical Characteristics’’ table are not guaranteed at the absolute maximum ratings. The ‘‘Recommended Operating Conditions’’ table will define the conditions for actual device operation.
