D Can be protected against damage or interference with a minimum of external circuitry D Voltage dependence of the car indicator lamps also compensated for lamp failure .

. With considerably reduced external circuitry, the integrated circuit U243B can be used as an instable multivibrator in.

The application circuit shows the operation of the U243B as a car-direction indicator signal generator. The flashing frequency is determined by the components Rt and Ct, and the frequency can be calculated from f1 The use of this application circuit .
