- A decade counter is a binary counter that is designed to count to 1010b.
- By changing the modes of Decade Counter IC, the chip can count up to other maximum numbers and return to zero.
- The Decade Counter IC consists of four master-slave JK flip-flops internally connected to provide a MOD-2 (count-to-2) counter and a MOD-5 (count-to-5) counter.
- Decade counter is one that counts in decimal digits, rather than binary. A decade counter may have each or other binary encodings.
Decade Counter IC - 74HC90
The 74HC Series 74HC90 Decade Counter IC having 4.75 to 5.25V Supply Voltage with 8mA Low Level and - 0.4mA High-Level Output Current. It is a simple counter, it can count from 0 to 9 cyclically in its natural mode. It counts the input pulses and the output is received as a 4-bit binary number through pins QA, QB, QC, and QD. The binary output is reset to 0000 at every tenth pulse and the count starts from 0 again.
Used For Power amplifiers, Small-signal amplifiers, Operational amplifiers, Microwave amplifiers, RF and IF amplifiers, Voltage comparators, Multiplier.

ADDITIONAL RESOURCES
1.What is the working of IC 7490?
- The integrated circuit 7490 is a 4-bit ripple-type decade counter. It is made up of four master/slave flip-flops that are internally linked to form a divide-by-two and a divide-by-five section. On a high-to-low clock transition, each section has a separate clock input that changes the counter's output states.
2.How to use 74LS90?
- The 74LS90 counting sequence is triggered on the clock signal's negative going edge, that is, when the clock signal CLK changes from logic 1 (HIGH) to logic 0. (LOW). R1 and R2 are counter "reset" pins, whereas S1 and S2 are set pins.
