U243B-FP Datasheet (TEMIC Semiconductors) - Warning or Car-Direction Indicator

U243B-FP, Warning or Car-Direction Indicator

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 ensures damage and interference protection accorda
