Expending Your MCU input/output pins with very cheap and effective solution Using Shift Registers 74HC165 & 74HC595 Families
Introduction: The purpose of this library is to control both TTL/CMOS integrated circuits “ICs†74HC165 and 74HC595 to expand the microcontrollers’’ input/output pins with low cost and effective solution.
What is the function of 74HC165?
It is parallel in, serial out IC which requires only 3 MCU’s pins in order to be controlled so it provide you with 8 inputs. So you will save with this IC 8 – 3 = 5 pins. However, if you cascade more ICs of the same series then you will add 8 inputs times the number of cascaded ICs with no changing with MCU interface. For example, if you use 2 ICs of 74HC165 then you will get 8 x 2 = 16 inputs
What is the function of 74HC159?
It is serial in, parallel out ICs which requires only 3 pins from the MCU in order you can control it. It simply let you to expand your controller with 8 additional output pins as a result you will save 8 – 3 = 5 pins. On the other hand, you can cascade as many as you wish of the same IC series with no change with the MCU interface but only expanding the outputs with 8 times the number added of the ICs.
