Pins of 74HC595 and their functions:

• Q0-Q7: 8-bit parallel data output pins, able to control 8 LEDs or 8 pins of 7-segment display directly.

• Q7’: Series output pin, connected to DS of another 74HC595 to connect multiple 74HC595s in series

• MR: Reset pin, active at low level;

• SHcp: Time sequence input of shift register. On the rising edge, the data in shift register moves successively

one bit, i.e. data in Q1 moves to Q2, and so forth. While on the falling edge, the data in shift register remain

unchanged.

• STcp: Time sequence input of storage register. On the rising edge, data in the shift register moves into memory

• CE: Output enable pin, active at low level.

• DS: Serial data input pin

• VCC: Positive supply voltage.

• GND: Ground.

Example

• 5.9 ShiftOut(LED) (Basic Project)
