IC 74595, 74HC595N, Shift Register, 8-Bit Serial to Serial/Parallel
Non-returnable
BD 2.000
The 74HC595 consists of an 8−bit shift register and an 8−bit D−type latch with three−state parallel outputs. The shift register accepts serial data and provides a serial output. The shift register also provides parallel data to the 8−bit latch. The shift register and latch have independent clock inputs. This device also has an asynchronous reset for the shift register. The HC595 directly interfaces with the SPI serial data port on CMOS MPUs and MCUs.

- Pin # 1 to Pin # 7 are Output Pins Q1 - Q7.
- Pin # 15 is also Output Pin Q0.
- Pin # 8 is Ground.
- Pin # 9 is Q7' (OutPut Serial Data).
- Pin # 10 is Master Reset.
- Pin # 11 is SHCP which is short for Shift Register Clock Input.
- Pin # 12 is STCP which is short for Storage Register Clock Input.
- Pin # 13 is OE which is Output Enable.
- Pin # 14 is DS which is Serial Data input.
- Pin # 16 is Vcc where we have to supply the power +5V.
- You can quite easily interface this shift register with different microcontrollers such as Arduino, PIC Microcontroller, Atmel etc.
Applications of 74HC595
It has a wide range of applications, especially in LED Boards. You must have seen the large LED boards where we have to control a lot of LEDs with a single microcontroller, 74HC595 is used in such projects a lot.
