  3. by Shyam Tiwari EDN The need for a compact telemetry system poses a challenge for designing a small, light, low-component-count system. Interfacing serial data from the microprocessor is also difficult because most low-cost RF transmitters do not ...

  4. Raju Baddi EDN When designing logic for higher-than-usual supply voltages, such as 24 V, you can use a voltage regulator with a standard logic family and interface it through level shifters. Alternatively, if the logic is not too complex and the ...

    Bob Marshall EDN In new mixed-voltage systems, it is often necessary to level-shift a control signal from a high level to a low level. An open-drain device, such as the 74LVC2G07 , easily performs this shift. However, when a bidirectional signal ...
