7490 IC is a Decade Counter IC. This is an original component suitable for both Education and Industrial purpose. For Bulk Inquiry, get in touch with us for wholesale price.
74LS90 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 count starts from 0 again.
Used For Power amplifiers, Small-signal amplifiers, Operational amplifier, Microwave amplifier, RF and IF amplifier, Voltage comparator, Multiplier.
Order fulfilled by Just Electronics, your reliable partner for all your electronic component needs for Industrial & Educational Purposes.
Features
- 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.
