74HC594D,112 Equivalent & Substitute Parts

Part Overview

The 74HC594D,112 is an 8-bit shift register logic IC manufactured by Nexperia USA Inc. in a 16-SOIC surface mount package. This component functions as a serial-to-parallel converter with push-pull output configuration, commonly used in digital logic applications requiring data serialization and parallel output conversion.

The 74HC594D,112 is classified as obsolete, making equivalent substitute parts necessary for ongoing design support, production continuity, and component sourcing. Active and last-time-buy alternatives are available from multiple manufacturers including Texas Instruments and Diodes Incorporated, all maintaining identical functional and electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74HC594D,112 is determined by strict equivalence across the following critical parameters:

• Logic Type: Shift Register
• Bit Configuration: 1 Element, 8 Bits per Element
• Output Configuration: Push-Pull
• Functional Capability: Serial to Parallel conversion
• Supply Voltage Range: 2V to 6V minimum compatibility
• Package Type: 16-SOIC surface mount
• RoHS3 Compliance: Required
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed maintain these core specifications. Variations in operating temperature range, packaging format (tape & reel vs. tube vs. cut tape), and product status (active vs. discontinued) do not affect functional interchangeability at the component level.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete 74HC594D,112, the following selection criteria apply:

Primary Recommendation: 74HC594S16-13 (Diodes Incorporated) or SN74HC594DWR (Texas Instruments). Both parts are active status with full RoHS3 compliance and unlimited moisture sensitivity rating. The 74HC594S16-13 maintains the extended operating temperature range (-40°C to 125°C) matching the original specification, while SN74HC594DWR operates to -40°C to 85°C.

Alternative Options: SN74HC594DR (Texas Instruments, active status) provides equivalent functionality with standard cut tape and Digi-Reel packaging options. SN74HC594DT remains available in limited inventory but is discontinued at DiGi Electronics.

Last-Time-Buy Consideration: SN74HC594DW (Texas Instruments) is designated last-time-buy status and should be evaluated only for legacy production runs with defined end-of-life dates.

All substitute parts maintain identical logic functionality, push-pull output configuration, 2V to 6V supply voltage compatibility, and 16-SOIC package footprint. Selection should prioritize active-status parts for new designs and ongoing production.

Frequently Asked Questions (FAQ)

Q: Can the 74HC594S16-13 directly replace the 74HC594D,112 in existing PCB designs?

A: Yes. Both parts use the 16-SOIC (0.154", 3.90mm Width) package with identical pinout and functional specifications. No PCB layout modifications are required.

Q: What is the difference between the operating temperature ranges of the substitute parts?

A: The 74HC594S16-13 operates from -40°C to 125°C, matching the original 74HC594D,112 specification. Texas Instruments variants (SN74HC594DR, SN74HC594DT, SN74HC594DW, SN74HC594DWR) operate from -40°C to 85°C. For applications requiring the full -40°C to 125°C range, the 74HC594S16-13 is the appropriate selection.

Q: Does packaging format (tube vs. tape & reel vs. cut tape) affect component functionality?

A: No. Packaging format affects only handling, storage, and supply chain logistics. Functional performance and electrical characteristics remain identical regardless of packaging format.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance and unlimited moisture sensitivity level (MSL 1), matching the original 74HC594D,112 environmental and regulatory certifications.

Q: Which substitute part has the highest current inventory availability?

A: The 74HC594S16-13 (Diodes Incorporated) has 50,300 units in stock, providing the highest availability among all listed alternatives.

Q: Can I use SN74HC594DT or SN74HC594DW for new production designs?

A: SN74HC594DT is discontinued at DiGi Electronics and should not be selected for new designs. SN74HC594DW is designated last-time-buy and is suitable only for legacy production with defined end-of-life schedules. For new designs, select active-status parts: 74HC594S16-13, SN74HC594DR, or SN74HC594DWR.
