How do you cascade two 74193?

Answer 1

To cascade two 74193 4-bit binary counters, connect the carry-out (CO) pin of the first counter to the carry-in (CI) pin of the second counter. Additionally, ensure that both counters share the same clock signal for synchronized counting. Reset both counters simultaneously with a common reset signal when needed. This configuration allows the first counter to increment the second counter upon reaching its maximum count, effectively creating an 8-bit counting system.
