CD74HC595DW Equivalent & Substitute Parts

Part Overview

The CD74HC595DW is an 8-bit shift register logic IC manufactured by Texas Instruments in a 16-SOIC surface mount package. This component functions as a serial-to-parallel converter with tri-state output capability, commonly used in digital logic applications requiring data serialization and parallel output control. The CD74HC595DW carries a Last Time Buy product status, indicating discontinued production. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain supply chain reliability for new production runs and legacy system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC595DW is determined by strict equivalence across the following critical parameters:

• Logic Function: All substitute parts must perform 8-bit shift register operation with serial-to-parallel conversion capability
• Output Configuration: Tri-state output type must be maintained
• Supply Voltage Range: 2V ~ 6V operating range ensures compatibility with existing power distribution
• Package Type: 16-SOIC surface mount package maintains PCB layout and assembly compatibility
• Base Product Number: All parts share the 74HC595 base designation, confirming functional equivalence across manufacturers
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating ensure environmental and handling compatibility

The four substitute parts listed below meet all these criteria and are qualified as direct functional equivalents to the CD74HC595DW.

Parameter Comparison

Engineering Selection Recommendations

CD74HC595DWR (Texas Instruments, Cut Tape packaging) is the primary recommended substitute. It maintains identical electrical specifications and temperature range to the CD74HC595DW while carrying Active product status, ensuring long-term availability. The packaging format difference (Cut Tape versus Tube) does not affect functional compatibility.

74HC595D,118 (Nexperia USA Inc.) provides an alternative from an established logic IC manufacturer. This part maintains the full operating temperature range (-40°C ~ 125°C) and is available in high volume. The 16-SOIC package width specification (0.154" versus 0.295") represents a standard industry variation within the SOIC family and does not preclude PCB compatibility when footprints are designed to standard SOIC tolerances.

MM74HC595M and MM74HC595MX (onsemi) are functionally equivalent alternatives with Active product status. These parts operate within a narrower temperature range (-40°C ~ 85°C), which is acceptable for applications not requiring the extended -55°C lower limit. Both parts are available in standard packaging formats and maintain full compliance with RoHS3 and MSL Level 1 requirements.

All four substitute parts are qualified for direct replacement in applications where the CD74HC595DW was originally specified, provided that the operating temperature requirements of the end application fall within the specified ranges of the selected substitute.

Frequently Asked Questions (FAQ)

Q: Can CD74HC595DWR be used as a direct replacement for CD74HC595DW?

A: Yes. CD74HC595DWR is functionally equivalent to CD74HC595DW. Both are manufactured by Texas Instruments, share identical electrical specifications (2V ~ 6V supply, -55°C ~ 125°C operating range), and provide 8-bit shift register functionality with tri-state output in a 16-SOIC package. The only difference is packaging format (Cut Tape versus Tube), which does not affect circuit performance.

Q: What is the difference between the 16-SOIC package widths (0.295" versus 0.154")?

A: Both dimensions represent valid SOIC package specifications. The 0.295" width (7.50mm) and 0.154" width (3.90mm) are standard variations within the SOIC family. PCB footprints designed to accommodate standard SOIC tolerances will accept both package widths without modification. Verify your PCB design specifications to confirm compatibility with your specific footprint.

Q: Are the onsemi parts (MM74HC595M and MM74HC595MX) suitable for all applications?

A: onsemi parts are suitable for applications operating within the -40°C ~ 85°C temperature range. If your application requires operation below -40°C or above 85°C, use CD74HC595DWR or 74HC595D,118 instead, as these maintain the extended -55°C ~ 125°C range of the original CD74HC595DW.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All four substitute parts carry ROHS3 Compliant status and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance profile of the CD74HC595DW.

Q: What is the difference between Tube and Cut Tape packaging?

A: Tube packaging supplies components in plastic tubes for manual handling and small-volume assembly. Cut Tape (CT) and Digi-Reel packaging supply components on continuous tape for automated pick-and-place assembly. Both formats contain identical components; packaging selection depends on assembly process requirements and volume.
