SN74HC595DBR

Shift Registers Overview

The SN74HC595DBR is an 8-bit serial-in, serial/parallel-out shift register manufactured by Texas Instruments. It belongs to the SN74HC series of high-speed CMOS logic devices and features three-state outputs. The component operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -40°C to +85°C. It is housed in a 16-pin SSOP package designed for surface-mount technology applications.

Shift Registers Feature Summary

• Converts serial input data into parallel output using internal shift and storage registers
• Provides three-state outputs controlled by an active-low output enable signal
• Includes independent clock inputs for the shift register and storage register
• Features an asynchronous clear input that resets the shift register

Shift Registers Applications

• Microcontroller I/O expansion for controlling multiple peripherals with limited pins
• LED display matrix scanning and multiplexing systems
• Industrial control panels requiring remote status indication
• Data acquisition systems needing additional digital output channels

Shift Registers Procurement Notes

Verify the specific suffix 'DBR' corresponds to the SSOP-16 package and tape-and-reel packaging configuration. Confirm RoHS compliance status as indicated in official documentation. Ensure the ordering part number matches the required logic family specifications before finalizing procurement orders.

Shift Registers Selection Notes

Select this component when a compact surface-mount solution is required for serial-to-parallel conversion. The HC logic family offers compatibility with standard 5V and lower voltage logic levels. Consider the SSOP package dimensions against available PCB real estate constraints during the design phase.

Shift Registers Part Context

This device is part of the broader SN74HC595 family, which includes variants with different packages such as SOIC or TSSOP. It serves as a fundamental building block for digital logic circuits requiring data serialization capabilities. The component is widely used in embedded systems where pin count optimization is critical.
