Quad low-to-high voltage translator with 3-state outputs

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 (VSS) and separate positive supplies for the inputs (VDD(A)) and the outputs (VDD(B)). VDD(A) must always be less than or equal to VDD(B), even during power turn-on and turn-off.

Each input protection circuit is terminated between VDD(B) and VSS. This allows the input signals to be driven from any potential between VDD(B) and VSS, without regard to current limiting. When driving from potentials greater than VDD(B) or less than VSS, the current at each input must be limited to 10 mA.

It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input.


  • Fully static operation
  • 5 V, 10 V, and 15 V parametric ratings
  • Standardized symmetrical output characteristics
  • Inputs and outputs are protected against electrostatic effects
  • Specified from -40 °C to +85 °C
  • Complies with JEDEC standard JESD 13-B
