U2640B General Description
With the U264xB, TEMIC Semiconductors developed a family of intermittent- and wipe/wash control circuits for windshield or backlite wiper systems with identical basic functions. The circuit design provides the possibility to generate "x" versions using different metallization masks. Thus, it is easy to verify a broad range of time sequences which can be set independently of each other.
