Counters

Counters are used to count pulses on an input pin (usually labelled '>'). The count is shown on the outputs, most often in binary form. After the count reaches its maximum value it returns to zero.

The count may be shown on the output pins in one of 3 ways, depending on the specific counter used:

1. Binary representation: each output pin represents a binary digit ('bit').
2. Pin-for-each-value: separate output pins on the counter represent each possible count value. Only one pin can be active at a time.
3. Decoded for 7-segment display: the count is shown on the pins in a way that matches the connections of a 7-segment display part.
