Working Principles

The CD74HC670M96 is a digital counter integrated circuit that counts and stores digital signals. It consists of four independent 4-bit counters, each capable of counting from 0 to 15. The counters can be enabled or disabled using the count enable (CE) input. The master reset (MR) input resets all counters to their initial count value.

The counters can be loaded with an initial count value in parallel using the P0-P3 inputs. The count value can be incremented by applying clock pulses to the CLK0-CLK3 inputs. The outputs QA-QD represent the current count value of each counter.

The CD74HC670M96 also features ripple carry outputs (RCO0-RCO3), which allow for cascading multiple counters to increase the counting range. When the maximum count value is reached, the ripple carry output generates a carry signal that can be connected to the next counter's clock input.
