Counter ICs

Indeed, counters are so important in so many applications that many different kinds of counter ICs have been designed for both TTL and CMOS logic families. Some count up for clocks and time intervals; others count down to show time remaining until some event. Some are specifically designed to count in decimal mode, while others count in binary, and still others have selectable counting ranges. The list of capabilities and options is quite large, leaving the circuit designer with only the task of selecting the particular IC that best suits the need.
