3-state hex non-inverting buffer
DESCRIPTION
The HEF40097B is a hex non-inverting buffer with 3-state
outputs. The 3-state outputs are controlled by two enable
inputs (EO
4
and EO
2
). A HIGH on EO
4
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 EO
2
causes the outputs of the remaining two
buffer elements to assume a high impedance or
OFF-state, regardless of the other input conditions.
