Shift Registers

8-bit shift registerSerial to parallelSchmitt triggerTri-state outputsSOT-23-THIN2 V to 6 V

SN74HCS595DYYR is a 16-pin 8-bit serial-in, parallel-out shift register for GPIO expansion and buffered parallel output control from a 2 V to 6 V supply.

Best for

  • GPIO output expansion
  • LED matrix control
  • 7-segment display control
  • Cascaded serial output control

Avoid if

  • The design requires defined output states immediately at power-up without external initialization.
  • Required load current exceeds device and package current limits.

Check before use

  • Verify the SOT-23-THIN DYY land pattern and pin orientation.
  • Verify total VCC and GND current for all enabled outputs.
  • Clear the shift register and transfer the cleared data to the storage register during initialization.
