The CD4071BM, CD4072BM and CD4075BM OR Gates provide the system designer with direct implementation of the positive-logic OR function and supplement the existing family of CMOS gates.
The CD4073BM, CD4081BM and CD4082BM are AND gates, provide the system designer with direct implementation of the AND function and supplement the existing family of CMOS gates.
The CD4093BM is consists of four Schmitt-trigger circuits. Each circuit functions as a two-input NAND gate with Schmitt-trigger action on both inputs. The gate switches at different points for positive- and negative-going signals.
