74VHC595SJ Equivalent & Substitute Parts

Part Overview

The 74VHC595SJ is an 8-bit shift register logic IC manufactured by onsemi, designed for serial-to-parallel data conversion applications. This component features tri-state output configuration and operates across a 2V to 5.5V supply voltage range. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional and electrical compatibility for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74VHC595SJ are qualified based on the following critical parameters that determine functional and electrical interchangeability:

• Logic Type: Shift Register (8-bit, single element)
• Output Type: Tri-State configuration
• Function: Serial to Parallel and Serial conversion capability
• Voltage Supply Range: 2V ~ 5.5V minimum compatibility
• Mounting Type: Surface Mount
• Package Type: 16-SOIC pinout compatibility
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed maintain these core electrical and mechanical specifications. Variations in operating temperature range and product status are noted but do not affect functional substitution within the specified supply voltage and operating conditions of the 74VHC595SJ.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the 74VHC595SJ, the following substitution hierarchy is established based on product status and compliance certifications:

Primary Recommendation: SN74AHC595DR (Texas Instruments) - Active product status with ROHS3 compliance and extended operating temperature range (-40°C to 125°C). Tape & Reel packaging supports production volume requirements.

Secondary Recommendation: 74AHC595D,118 (Nexperia USA Inc.) - Active product status with ROHS3 compliance and extended operating temperature range. Tape & Reel packaging available with high inventory levels.

Alternative Option: SN74AHC595D (Texas Instruments) - ROHS3 compliant with extended operating temperature range, though marked as discontinued at DiGi Electronics. Suitable for applications where existing inventory is available.

All three substitute parts maintain electrical equivalence within the specified 2V to 5.5V supply voltage range and preserve the 8-bit tri-state shift register functionality. Package width variations (0.209" versus 0.154") require PCB layout verification for physical fit.

Frequently Asked Questions (FAQ)

Q: Can the 74VHC595SJ be directly replaced with the SN74AHC595DR?

A: Yes. Both parts share identical logic type (8-bit shift register), output type (tri-state), function (serial to parallel conversion), and supply voltage range (2V ~ 5.5V). The 16-SOIC pinout is compatible. PCB layout must accommodate the package width difference (0.209" versus 0.154").

Q: What is the significance of the extended operating temperature range in substitute parts?

A: The substitute parts operate from -40°C to 125°C, compared to the 74VHC595SJ range of -40°C to 85°C. This extended range provides additional thermal margin for applications operating at elevated temperatures but does not affect substitution compatibility for designs within the original -40°C to 85°C specification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 74AHC595D,118, SN74AHC595D, and SN74AHC595DR are all ROHS3 compliant. The original 74VHC595SJ compliance status was not specified in the provided data.

Q: Does package width variation affect electrical performance?

A: No. The package width difference (0.209" for 74VHC595SJ versus 0.154" for substitute parts) is a physical dimension only. Electrical performance and pinout compatibility remain unchanged. PCB footprint and layout spacing must be verified during design integration.

Q: Which substitute part has the best availability?

A: The 74AHC595D,118 (Nexperia) shows the highest inventory level at 24,258 pieces. The SN74AHC595DR (Texas Instruments) is also actively stocked with 3,455 pieces available.

Q: Can substitute parts be used interchangeably in existing designs?

A: Yes, provided the PCB layout accommodates the package width variation. All electrical specifications, pinout configurations, and functional characteristics are equivalent within the 2V to 5.5V supply voltage range.
