1. General description
The HEF4104B is a quad low voltage-to-high voltage translator with 3-state outputs. It
provides the capability of interfacing low voltage circuits to high voltage circuits. For
example low voltage Local Oxidation Complementary MOS (LOCMOS) and
Transistor-Transistor Logic (TTL) to high voltage LOCMOS. It has four data inputs (A0 to
A3), an active HIGH output enable input (OE), four data outputs (B0 to B3) and their
complements (B0 to B3).
With OE = HIGH, the outputs B0 to B3 and B0 to B3 are in the low impedance ON-state,
either HIGH or LOW as determined by the inputs A0 to A3. With OE = LOW, the outputs
B0 to B3 and B0 to B3 are in the high-impedance OFF-state.
It uses a common negative supply (V
SS
) and separate positive supplies for the inputs
(V
DD(A)
) and the outputs (V
DD(B)
). V
DD(A)
must always be less than or equal to V
DD(B)
, even
during power turn-on and turn-off. For the permissible operating range of V
DD(A)
and
V
DD(B)
see
Figure 4
.
Each input protection circuit is terminated between V
DD(B)
and V
SS
. This allows the input
signals to be driven from any potential between V
DD(B)
and V
SS
, without regard to current
limiting. When driving from potentials greater than V
DD(B)
or less than V
SS
, the current at
each input must be limited to 10 mA.
It operates over a recommended V
DD
power supply range of 3 V to 15 V referenced to V
SS
(usually ground). Unused inputs must be connected to V
DD
, V
SS
, or another input.
2. Features and benefits
