7490 is a Binary coded decimal counter and counts up to ten digits. Being binary counter it counts in binary digit like 0000, 0001, etc. The IC contains 4 master-slave flip-flops and some gating circuits to provide a divide-by-two counter and three-stage binary counter for which counter is divided by 5. The counter circuit gets reset for every new clock.

The 7490 IC is a decade counter, which means it counts in decimal digits, specifically from 0 to 9. It functions by incrementing its count by 1 each time it receives a clock pulse. The IC contains four internal flip-flops and uses a series of logic gates to count.

Each time a clock pulse is received, it advances to the next sequential output state. When it reaches “9” (binary equivalent: 1001), the next clock pulse resets the count back to “0” (binary equivalent: 0000) and simultaneously causes a carry-out signal, which can be utilized for cascading multiple counters together to count beyond 9.

The 7490 IC usually has four outputs (labeled Q A, Q B, Q C, and Q D) that represent the BCD (Binary-Coded Decimal) count. It can count up, down, or both (up and down) based on its configuration using external circuitry.

This IC is widely used in digital circuits for applications like frequency dividers, timer circuits, and in systems requiring sequential counting.
