HEF4104B Quad low-to-high voltage translator with 3-state outputs Rev. 8 11 November 2011 Product data sheet 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 (B0to B3). With OE = HIGH, the outputs B0 to B3 and B0to 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 B0to B3 are in the high-impedance OFF-state. It uses a common negative supply (V ) and separate positive supplies for the inputs SS (V ) and the outputs (V ). V must always be less than or equal to V , even DD(A) DD(B) DD(A) DD(B) during power turn-on and turn-off. For the permissible operating range of V and DD(A) V see Figure 4. DD(B) Each input protection circuit is terminated between V and V . This allows the input DD(B) SS signals to be driven from any potential between V and V , without regard to current DD(B) SS limiting. When driving from potentials greater than V or less than V , the current at DD(B) SS each input must be limited to 10 mA. It operates over a recommended V power supply range of 3 V to 15 V referenced to V DD SS (usually ground). Unused inputs must be connected to V , V , or another input. DD SS 2.
