CD74HC595DWR

Shift Registers Overview

The CD74HC595DWR is an 8-bit serial-in, parallel-out shift register manufactured by Texas Instruments. It belongs to the 74HC logic family and operates within a supply voltage range of 2 V to 6 V. The device features three-state output registers for effective bus driving. It is housed in a 16-pin SOIC surface-mount package with a standard operating temperature range of -40°C to +85°C.

Shift Registers Feature Summary

• Provides serial-to-parallel data conversion capabilities for digital signal processing.
• Features three-state outputs to facilitate connection to system buses without interference.
• Utilizes CMOS technology for low power consumption and high noise immunity.

Shift Registers Applications

• Display drivers requiring serial data input and parallel output control.
• Industrial control systems utilizing I/O expansion via daisy-chaining.
• Consumer electronics employing LED matrix or indicator arrays.

Shift Registers Procurement Notes

Verify the specific suffix 'DWR' confirms the SOIC-16 package and tape-and-reel packaging format. Ensure the component matches the 74HC series specifications rather than AHC or LV variants. Confirm RoHS compliance status as per the manufacturer's current documentation before finalizing procurement orders.

Shift Registers Selection Notes

Select this component when a through-hole alternative like the PDIP variant is unsuitable for the PCB layout. The SOIC-16 form factor supports automated surface-mount assembly processes. Consider the 74HC speed and voltage characteristics against system requirements compared to faster AHC or lower-voltage LV families.

Shift Registers Part Context

This part is a member of the Texas Instruments SN74HC595 family of 8-bit shift registers. It shares functional compatibility with other devices in the 74HC series while differing in physical package and mounting style. The DWR designation specifically identifies the surface-mount SOIC configuration within the broader product line.
