Each circuit contains four master/slave QUESTIONS: 1. Firstly, it is ideal for applications having low power consumption requirement. Presetting the counter to the number on preset data inputs (A-D) is accomplished by a low asynchronous parallel load (LOAD)\ input. SW2 is the reset switch. It is used to display numbers on seven segment displays and it increment the number by one, when a clock pulse is applied to its PIN 1. Thus, the count is reset and starts over again at "0000" producing a synchronous decade counter. It can be used for a variety of counter circuits and practical applications, like an LED chaser light circuit to even a non-contact AC detector circuit.. IC 4017 is a 16 pin IC. IC 7490 is a 4-bit, ripple-type decade counter. With each clock pulse the outputs advance to the next higher value, resetting to 0000 when the output is 1001 and a subsequent clock pulse is received. Counters are designed by grouping flip flops and applying a single clock signal to them. It consists of four master/slave flip-flops, which are internally connected to form a divide-by-two section and a divide-by-five section.
