SN74HC595DRE4

Shift Registers Overview

The SN74HC595DRE4 is an 8-bit serial-in, serial/parallel-out shift register manufactured by Texas Instruments. It belongs to the HC logic family and features 3-state outputs. The device operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -40°C to +85°C. It is housed in a 16-pin SSOP package and includes asynchronous reset functionality.

Shift Registers Feature Summary

• Provides serial-to-serial and serial-to-parallel data conversion capabilities for efficient I/O expansion.
• Features 3-state outputs that allow direct connection to system buses without additional interface hardware.
• Includes an asynchronous reset input to clear the shift register independently of clock signals.

Shift Registers Applications

• General-purpose I/O expansion in embedded systems
• Serial-to-parallel data conversion interfaces
• LED display driver circuits

Shift Registers Procurement Notes

Verify the specific suffix 'E4' against the manufacturer's current datasheet to confirm compliance with RoHS directives and material composition requirements. Ensure the SSOP-16 package dimensions match the target PCB footprint constraints before finalizing procurement orders.

Shift Registers Selection Notes

Select this component when a CMOS-compatible shift register with 3-state outputs is required for low-power applications. The HC series offers standard switching speeds suitable for general digital logic interfacing. Verify that the 2 V to 6 V supply voltage range aligns with the target system's power rails.
