Quadruple low to high voltage translator with 3-state outputs
DESCRIPTION
The HEF4104B quadruple low voltage to high voltage translator with 3-state outputs provides the capability of interfacing low voltage circuits to high voltage circuits, such as low voltage LOCMOS and TTL to high voltage LOCMOS. It has four data inputs (I0to I3), an active HIGH output enable input (EO), four data outputs (O0to O3) and their complements (O0to O3).
With EO HIGH, O0to O3and O0to O3are in the low impedance ON-state, either HIGH or LOW as determined
to I3; with EO LOW, O0to O3and O0to O3are in the
by I
0
high impedance OFF-state.

or less than VSS, the current at each input must
