Shift Register Breakout – 74HC595 Board Module

Shift Register Breakout – 74HC595 Board Module

Description:

Shift Register Breakout – 74HC595 Board Module  This breakout board for the 74HC595 shift register IC in a SOIC package allows for efficient data input and latching, helping to save I/O pins on your microcontroller. Each pin from the IC is accessible via standard 0.1″ headers. The Serial In and Out pins are located on opposite sides of the board, and additional pins are provided for daisy-chaining multiple shift register boards.

The 74HC595 features an 8-bit serial-in, parallel-out shift register that connects to an 8-bit D-type storage register with tri-state outputs. Both registers are clocked independently. The IC also includes a direct clear input (SRCLR), a serial input (SER), and a serial output for cascading. When the output enable (OE) is set high, the outputs enter a high-impedance state.

The clocks for the shift register (SRCLK) and storage register (RCLK) are activated on the rising edge. When these two clocks are connected, the shift register remains one clock pulse ahead of the storage register.

Features

• SOIC version of the 74HC595 shift register IC.
• The Serial in and out pins are on opposite sides of the board.
• All pins from the IC are broken out to standard 0.1″ spaced headers.
• Dimension: Approx. 30*26*4mm

Package Includes

• 1x 74HC595 Shift Register Breakout Module

Shift Register Breakout – 74HC595 Board Module Overview

The Shift Register Breakout – 74HC595 Board Module is a compact breakout board featuring the SOIC-packaged 74HC595 8-bit serial-in, parallel-out shift register. It simplifies expanding digital outputs on microcontrollers by providing independent clock, latch, clear and enable controls with all pins broken out to 0.1″ headers.

Key Features of Shift Register Breakout – 74HC595 Board Module

• All 16 pins of the 74HC595 IC brought out to standard 0.1″ spaced headers
• SOIC package version saves PCB space and improves heat dissipation
• Serial In and Serial Out pins on opposite sides for easy daisy-chaining
• Independent control of shift clock (SRCLK), latch (RCLK), clear (SRCLR) and output enable (OE)
• Supports cascading multiple boards to expand outputs beyond eight channels
• Genuine product with fast shipping from Zbotic

Applications and Use Cases

• Expanding I/O pins on Arduino, Raspberry Pi or other microcontrollers
• Driving LED matrices, bar-graph displays and seven-segment modules
• Controlling arrays of relays, solenoids or indicators
• Building digital output expanders in robotics or automation projects
• Daisy-chained control systems requiring synchronized latch and clock signals

How to Use Shift Register Breakout – 74HC595 Board Module

Wire VCC and GND to your power rails, then connect SER, SRCLK and RCLK pins to your microcontroller’s digital outputs. Use SRCLR to asynchronously clear the register and OE to enable or tri-state outputs. Send data bits serially by toggling SRCLK, then pulse RCLK to latch outputs. For additional outputs, connect the Serial Out pin of one board to the Serial In of the next.

Frequently Asked Questions

Can I cascade multiple 74HC595 breakout boards?

Yes. The Serial Out (QH’) pin is positioned on the side opposite the Serial In. Connect it to the Serial In of the next board to daisy-chain additional registers seamlessly.

What supply voltage does the breakout board require?

The breakout board supports a supply range of 2V to 6V, matching the typical operating range of the 74HC595 IC. Most users power it at 5V or 3.3V to match their microcontroller logic levels.

Is the pin spacing compatible with breadboards?

Absolutely. All header pins are spaced at 0.1″ (2.54 mm), making this breakout board plug-and-play with standard solderless breadboards and perf boards.
