WebNov 18, 2024 · The pin description of 7490 is as follows, Working of 7490 Decade Counter Circuit: It’s a BCD counter it can count from 0 to 9 (10 states), hence it is called a mod-10 counter. It has two separate counters, a mod 2 counter, and another mod 5 counter. Together they form a mod 10 counter. Web74LS93 or SN74LS93 is a 4-bit binary counter. Counters have a major role in every electronics device. The output of the counters can be used in multiple devices as pulse …
