Shift registers are often used to increase the number of I/O pins on a microcontroller. For example, If your project needs to control 16 individual LEDs, you will, of course, require 16 pins of an Arduino, which is not possible. This is where the shift register comes in handy. With two shift registers connected in series, you can control 16 LEDs wi...
The 74HC595 has two 8-bit registers (which can be thought of as “memory containers”). The first is referred to as the Shift Register, and the second as the Storage/Latch Register. Every time the 74HC595 receives a clock pulse, two things happen: 1. The bits contained in the shift register are shifted to the left by one position. Bit 0’s value is pu...
It is important to note that several companies manufacture the same 74HC595 chip. In this article, we will discuss the ubiquitous SN74HC595Nfrom Texas Instruments. If you happen to have a different one, carefully read the datasheet and make note of any differences. Let’s take a look at its pinout. GNDis the ground pin. VCCis the power supply for th...
Now that we know the basics of how 74HC595 works, we can start connecting it to our Arduino! Start by putting the shift register on your breadboard. Make sure that each side of the IC is on a different side of the breadboard. With the little U-shaped notch facing up, pin 1 of the chip is to the left of this notch. Connect pins 16 (VCC) and 10 (SRCL...
Here is an example sketch that turns on each LED in turn until they are all on, then turns them all off and the cycle repeats. First, try out the sketch, and then we’ll go over it in detail. After uploading the code to the Arduino, you should see the following output:
Here’s another project based on the same setup but with a slight variation: we manipulate the OE pin on the IC to control the brightness of the output LEDs! We already know that the OE (Output Enable) pin functions as a switch. When this pin is set to HIGH, the output pins are disabled (remember, it is active-low). When OE is set to LOW, the output...
Learn how to use the 74HC595 shift register, a popular chip for adding more I/O pins to your Arduino or microcontroller. See the pinout, the working principle, and the interface with Arduino code examples.
The 74HC595 is an high speed CMOS device. An eight bit shift register accpets data from the serial input (DS) on each positive transition of the shift register clock (SHCP). When asserted low the reset function ( ) sets all shift register values to zero and is indepent of all clocks.

M74HC595 is a high speed CMOS device that combines an 8-bit serial in, parallel out shift register and an 8-bit D-type storage register with 3-state outputs. It has direct overriding clear, serial input, and serial output pins, and operates at VCC from 2 V to 6 V with low power dissipation and noise immunity.
MM74HC595 is a high-speed shift register that utilizes silicon-gate CMOS technology and can drive 15 LS-TTL loads. It has an eight-bit serial-in, parallel-out, shift register and an eight-bit D-type storage register with eight 3-state outputs. The device has direct-overriding clear, serial input, and serial output pins for cascading.
