It can be used in cascading applications by connecting multiple IC’s of CD4015.Due to its multiple outputs, it is used in LED matrix projects in which LEDs are interfaced with the outputs.It can be used in serial to parallel data conversion as it has serial input and parallel data outputs.In the end, apply the clock signal, as you can see, logic zero appears on pin Q0 and other pins sequentially on every positive edge of the clock, Applications.Now change the serial data input to logic low,.As you can see, as soon as we apply a clock signal to CD4015, data will start to shift on the output pins. After that, apply the clock signal and see the output of the shift register.Hence, on the first positive edge, pin Q0 will become one, on the second positive edge of the clock, pin Q1 will become high, and so on.First makes serial data input pin logic high, that means, logic one will transfer to each stage on every positive edge of the clock cycle, Because in serial mode, data transfer bit by bit.Now let’s see proteus simulation working,.We can use the Probe state of proteus to see the output of Q0 to Q3.

Because, switching from zero to one, will provide a positive edge, to shift register. For simulation purposes, We will use the toggle switch to provide a positive edge.We will provide clock signal and serial data input through these logic states. For simulation purposes, we are using logic states and logic probes of proteus.You can use it in LED chasers and LED drivers. Due to its large number of outputs, you can expand the I/O capability using this IC. It can be used in applications that require controlling multiple outputs in a parallel mode as it has 8 parallel outputs. It can also be used as an I/O expander to control multiple outputs. It is commonly used in high voltage applications as it has a wide operating voltage range. Maximum Clock Frequency is 12Mhz at 10V Alternative options.Operating voltage range is 3V to 18V with medium speed operation.Fully static operation with a clock frequency of 8.5Mhz at 15V.Dual 4-bit IC having serial Inputs and a parallel output Shift register composed of 8 master-slave flip flops.Other alternative and Equivalent shift Registers: 74HC595, CD4035, CD4014, CD4022 CD4015 Static Shift Register Features Pin Number Pin Name Pin Description 1 Clock B Clock pulse signal for shift register B 2, 11, 12, 13 1B, 2B, 3B, 4B Output pins for shift register B 3, 4, 5, 10 1A, 2A, 3A, 4A Output pins for shift register A 6 RESET A Responsible for resetting all the outputs of a shift register A 7 DATA A Input data pin for shift register A 8 Vss Negative power supply or ground of the circuit 14 RESET B Responsible for resetting all the outputs of a shift register B 15 DATA B Input data pin for shift register B 16 Vcc Power supply voltage Each pin, its number, and description are mentioned in the table below.
