General Description
These up down counters are monolithic complementary MOS (CMOS) integrated circuits The CD40192BM and CD40192BC are BCD counters while the CD40193BM and CD40193BC are binary counters
Counting up and counting down is performed by two count inputs one being held high while the other is clocked The outputs change on the positive-going transition of this clock
These counters feature preset inputs that are enabled when load is a logical ‘‘0’’ and a clear which forces all outputs to ‘‘0’’ when it is at logical ‘‘1’’ The
