74VHC595M Equivalent & Substitute Parts

Part Overview

The 74VHC595M is an 8-bit shift register with tri-state output manufactured by onsemi, housed in a 16-SOIC surface mount package. This component functions as a serial-to-parallel converter and is commonly used in digital logic applications requiring data shifting and parallel output control. The 74VHC595M is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74VHC595M is determined by strict adherence to the following parameters:

• Logic Type: Shift Register (8-bit)
• Output Type: Tri-State
• Function: Serial to Parallel, Serial
• Supply Voltage Range: 2V ~ 5.5V (minimum requirement)
• Package: 16-SOIC form factor
• Mounting Type: Surface Mount
• RoHS3 Compliance and MSL Level 1

Substitute parts are grouped into three categories based on their relationship to the main part:

Upgrade Substitutes maintain all electrical parameters while offering extended operating temperature ranges or improved product status (Active vs. Obsolete).

Direct Substitutes provide equivalent electrical and mechanical specifications with compatible packaging and performance characteristics.

Parametric Equivalents meet core functional requirements but may have minor variations in operating temperature or other non-critical parameters.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring the 74VHC595M, the following selection criteria apply based on product status and compliance:

Primary Selection (Active Status): MC74VHC595DR2G, SN74AHC595DR, and 74AHC595D,118 are all currently active products with full RoHS3 compliance and MSL Level 1 rating. These parts are recommended for new designs and ongoing production. MC74VHC595DR2G offers extended operating temperature range (-55°C ~ 125°C) compared to the original specification, providing additional thermal margin. SN74AHC595DR and 74AHC595D,118 maintain the same supply voltage and functional characteristics while offering improved temperature performance (-40°C ~ 125°C).

Secondary Selection (Discontinued Status): SN74AHC595D and SN74LV595AD are listed as discontinued at DiGi Electronics but remain functionally equivalent. These parts are suitable only for legacy system support or when inventory is available through alternative distribution channels.

All substitute parts maintain RoHS3 compliance, MSL Level 1 rating, and identical 16-SOIC packaging, ensuring direct mechanical and electrical compatibility with the original 74VHC595M design.

Frequently Asked Questions (FAQ)

Q: Can I use MC74VHC595DR2G as a direct replacement for 74VHC595M?

A: Yes. MC74VHC595DR2G is functionally equivalent with identical supply voltage (2V ~ 5.5V), logic type (8-bit shift register), output type (tri-state), and 16-SOIC package. The primary difference is extended operating temperature range (-55°C ~ 125°C vs. -40°C ~ 85°C) and active product status, making it suitable for new designs.

Q: What is the difference between 74VHC and 74AHC series parts?

A: Both series are 8-bit shift registers with tri-state output in 16-SOIC packages and identical supply voltage specifications (2V ~ 5.5V). The primary difference is the manufacturer and product line designation. 74AHC parts from Texas Instruments and Nexperia offer extended operating temperature ranges (-40°C ~ 125°C) compared to the original 74VHC595M (-40°C ~ 85°C).

Q: Is SN74LV595AD compatible with 74VHC595M?

A: SN74LV595AD meets the core functional requirements (8-bit shift register, tri-state output, 2V ~ 5.5V supply, 16-SOIC package) and is a parametric equivalent. However, it is discontinued at DiGi Electronics and has the same operating temperature range as the original part (-40°C ~ 85°C). Use only if inventory is available and legacy support is required.

Q: What packaging options are available for substitutes?

A: Substitute parts are available in two packaging formats: Tube and Tape & Reel (TR). Tube packaging is suitable for lower-volume applications, while Tape & Reel is standard for high-volume production. All parts maintain the same 16-SOIC form factor and are mechanically interchangeable.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original 74VHC595M specification.
