What is IC 7490?
IC 7490 is also known as BCD Counter, Decade Counter, and mod-10. These names are given based on the Functionality and Working Principle of IC 7490. In the discussion of Counter ICs, some basic terms will be used a lot. That’s why we need to know some basic terminology while Designing any of Counter.
What is ICIC 7490 dip?
IC 7490 is a 14 pin DIP (dual inline package) ic. The pin description of 7490 is as follows, Its 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.
How does a 7490 decade counter circuit work?
Working of 7490 Decade Counter Circuit: Its 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.
What is VCC and GND in ICS 7490?
Start with its input terminals VCC and GND are the input pins of ICs 7490 which is used to give power supply to the ICs. These input terminals generally present in all devices to give power supply to the devices. VCC stands for Voltage Common Collectors and in most cases, it is referred to as high voltage with respect to GND (Ground) terminal.
What is the output of the 7447A IC?
According to the 7447 datasheet the 7446A and 7447A ICs feature active-low outputs designed for driving common-anode LEDs or incandescent indicators directly. All of the circuits have full ripple-blanking input/output controls and a lamp test input.
