U840B Digital / Wipe-Wash Control

The circuits U840B (DIP8) and U840B-FP (SO8) are designed as interval wipe/ wash timer for automotive applications. The interval pause t3 can be set in a range from 0.8 s to 22 s by an external 30 kW potentiometer. All other time periods are determined by the basic frequency f0 of the oscillator. Th.
