Where to use 74HC595?
Do you ever wonder, how an embedded engineer controls hundreds of series or parallel connected light-emitting diodes with the help of a microcontroller that have very few general-purpose I/O pins? Additionally, You want to control more than 8 servo motors and you have only 2-3 GPIO pins of a microcontroller. How you will solve this problem? How you will control an LED Matrix of different dimensions such as 8×8, 16×16, 32×32 with minimum GPIO pins of a microcontroller? The simple answer is a 74HC595 shift register.
In most of the applications, you need more outputs for interfacing LEDs or any other devices such as seven segments, 16 segments, LED flasher, etc. This IC is very handy to use. For increasing the output pins, you can interface this IC with different microcontrollers such as Arduino Uno, PIC Microcontroller, Atmel, etc. You can use this IC in designing projects which require controlling multiple outputs.
How to use 74HC595?
74HC595 has eight outputs and 3 input pins which include a data pin, storage resistor clock pin, and shift register clock pin. Connect pin8 to ground and pin16 to +5V voltage supply.
The output enables pin (~OE) should be grounded to enable the output pins of the shift register. The master reset pin will clear the memory of a shift register if it is applied with a low signal. That’s why it should be kept high.
When the positive edge transition occurs on pin 11, the shift register will accept the inputs applied on the data line.
The outputs of the storage register are connected to the input pins of the D-latch/storage resistor.
These inputs are updated on the latch output when a positive edge transition occurs at pin 12.
