Product description

Shift Registers such as the 74HC595 (Serial-In, Parallel-Out) and 74HC165 (Parallel-In, Serial-Out) are used to expand the number of I/O ports in microcontroller systems. They are commonly applied when the number of available pins on a microcontroller is insufficient. Below is a technical overview of their applications and how they operate:

74HC165 – Parallel In, Serial Out - Application: Reading multiple digital inputs using few microcontroller pins. The 74HC165 reads 8 bits in parallel from digital sources and outputs them serially.

Typical use cases:

  •     Reading keypads (e.g., 4x4 matrices)
  •     Collecting status data from multiple digital sensors
  •     Expanding digital inputs in microcontroller applications

Advantages:

  • Requires only 3 microcontroller pins: Data (QH), Clock (CLK), and Latch (PL)
  • Can also be cascaded for additional input capacity

Operating principle: When PL (Parallel Load) is low, the 8 bits are latched from inputs D0–D7. These bits are then shifted out via QH using clock pulses on CLK.

 

74HC595 – Serial In, Parallel Out  - Application: Expanding the number of digital outputs. The 74HC595 receives data serially (bit by bit) and presents it in parallel on 8 output pins.

Typical use cases:

  • Driving LED matrices
  • Controlling 7-segment displays
  • Operating relays or other digital loads when output pins are limited
  • Implementing digital port expanders

Advantages:

  • Requires only 3 microcontroller pins: Data (SER), Clock (SRCLK), and Latch (RCLK)
  • Can be cascaded to increase the number of outputs (8, 16, 24 bits, etc.)

Operating principle: Transmit 8 bits serially via the SER input, synchronized with SRCLK. Once all bits are loaded, trigger RCLK (latch) to update the outputs Q0–Q7.
