MC10138

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Bi-Quinary Counter The MC10138 is a four bit counter capable of divide by two, five, or ten functions. It is composed of four set–reset master–slave flip–flops. Clock inputs trigger on the positive going edge of the clock pulse. Set or reset input override the clock, allowing asynchronous “set” or “clear.” Individual set and common reset inputs are provided, as well as complementary outputs for the first and fourth bits.
