Working Principle of 74LS164 Shift Register

  • ~MR is a low-input active master reset pin. The output will be in a low state until its state is low, regardless of what is at input A or B. As a result, it's also known as the Reset or Clear mode of operation. MR must be set to a high value to complete the procedure.

  • Serial data can be sent by either of the two input pins while using another pin as an active high allows data to be entered into other input pins. Any input pin that isn't in use needs to be set to high. Connecting two input pins is also conceivable.

  • When a clock transitions from low to high, Data moves one position to the right, and Q0 is filled with the AND of two data inputs at A and B.


Where to Use 74LS164

The 74LS164 Shift Register is an 8-bit serial-in, parallel-out device. It can receive (input), obtain data serially, and control output pins in parallel, which means it can receive (input), get data serially and control output pins in parallel. This is useful when our MCU/MPU does not have enough GPIO pins to control the needed number of outputs. It's frequently used in projects where a huge number of LEDs must be controlled by a microcontroller. Because it may operate as the data bit for LCDs, it can also be utilized to interface an LCD panel.


How to Use 74LS164

To extend GIPO functionality, the 74LS164 shift register is typically utilized with microcontrollers or microprocessors. The 74LS164 is a 14-pin integrated circuit with four inputs, eight outputs, power, and ground. A microcontroller with four lines is required for the 74LS164. There are three input pins: one for the clock, one for the clear, and two for the input (A & B). Input Pins A and B function as a logical AND gate, meaning it will read 1 if both pins are logic high (5 volts). To clear the full register at once, use the clear pin.
