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.

Each input protection circuit is terminated between

from any potential between V

to current limiting. When driving from potentials greater
than V
or less than VSS, the current at each input must
