COM-13699

Shift Registers Overview

The SparkFun COM-13699 is a breakout board featuring the SN74HC595N, an 8-bit serial-in, parallel-out shift register. This component allows for the expansion of digital output pins on microcontrollers by serializing data transmission. It operates within a supply voltage range compatible with standard logic levels and supports high-speed shifting capabilities. The board provides accessible connections for clock, latch, and data lines, facilitating integration into embedded systems requiring additional GPIO resources without consuming multiple processor pins.

Shift Registers Feature Summary

• Converts serial input data into parallel output signals to expand available digital control lines
• Enables daisy-chaining of multiple units for cascaded output expansion
• Provides dedicated clock and latch control inputs for precise timing synchronization

Shift Registers Applications

• Driving LED matrices or arrays with limited microcontroller pins
• Controlling multiple discrete outputs such as relays or indicators
• Expanding I/O capacity in embedded sensor networks

Shift Registers Procurement Notes

Verify the specific package type and pin configuration against your PCB footprint requirements. Confirm that the operating voltage range aligns with your system's logic levels. Ensure compatibility with your microcontroller's serial communication interface before finalizing procurement decisions.

Shift Registers Selection Notes

Select this component when serial-to-parallel conversion is required to minimize pin usage. Consider the maximum shift frequency and output drive capability relative to your load requirements. Evaluate the need for daisy-chaining if more than eight outputs are necessary for the design.

Shift Registers Part Context

This part belongs to the SN74HC595 series of shift registers, widely used in digital electronics for output expansion. It is commonly integrated into development boards and custom circuits where efficient pin management is critical. The component serves as a fundamental building block for controlling multiple peripherals from a single serial data stream.

Shift Registers Replacement Considerations

Compatible substitutes include other 8-bit shift registers from the same family, such as the SN74HC595N or equivalent parts from different manufacturers offering identical pinouts and functionality.
