DESCRIPTION

The HEF40098B is a hex inverting buffer with 3-state outputs. The 3-state outputs are controlled by two enable inputs (EO4 and EO2). A HIGH on EO4 causes four of the six buffer elements to assume a high impedance or OFF-state regardless of the other input conditions and a HIGH on EO2 causes the outputs of the remaining two buffer elements to assume a high impedance or OFF-state regardless of the other input conditions.
