Description
The MC10E/100E136 is a 6-bit synchronous, presettable, cascadable universal counter. The device generates a look-ahead-carry output and accepts a look-ahead-carry input. These two features allow for the cascading of multiple E136’s for wider bit width counters that operate at very nearly the same frequency as the stand alone counter.
