3-state hex inverting buffer

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.
