| Asynchronous Counter | Type of counter in which each flip-flop output serves as the clock input signal for the next flip-flop in the chain. |
| Binary Counter | Group of flip-flops connected in a special arrangement in which the states of the flip-flops represent the binary number equivalent to the number of pulses that have occurred at the input of the counter. |
| Decade Counter | Any counter capable of going through 10 different logic states. |
| Down Counter | Counter that counts from a maximum count downward to 0. |
| Modulus | The number of states through which a counter sequences before repeating. |
| Modulus N Counter (mod-n counter) | A counter with a modulus of N. |
| Synchronous Counter | Counter in which all of the flip-flops are clocked simultaneously. |
| Up Counter | Counter that counts upward from 0 to a maximum count. |
| Up/Down Counter | Counter that can count up or down depending on how its inputs are activated. |
