A two-digit counter is a simple electronic circuit designed to count and display numbers from 00 to 99 using ICs such as LM555 and Two CD4033 along with two 7-segment displays. This counter is used in applications such as digital clocks, scoreboards, and event counters. It typically consists of:
- Clock Generator: A timer IC like the LM555 generates clock pulses that drive the counter.
- Counting ICs: Two CD4033 decade counters are used. Each IC counts from 0 to 9 and drives a 7-segment display.
- Cascading: The first CD4033 handles the units place, and its overflow signal advances the second CD4033, which manages the tens place.
- Digit Display: Two common cathode 7-segment for digit display
