TPIC6C596D Equivalent & Substitute Parts

Part Overview

The TPIC6C596D is an 8-bit shift register manufactured by Texas Instruments, designed for serial-to-parallel data conversion applications. This device features open-drain outputs and operates across a 4.5V to 5.5V supply voltage range with an operating temperature span of -40°C to 125°C. The part is currently in Last Time Buy status, indicating limited availability and the necessity to identify equivalent alternatives for ongoing design requirements and production planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPIC6C596D is determined by the following critical parameters: logic type (shift register), number of bits per element (8 bits), output type (open drain), supply voltage range (4.5V to 5.5V), operating temperature range (-40°C to 125°C), and package compatibility (16-SOIC form factor).

Substitute parts are grouped into two categories:

Parametric Equivalents maintain identical electrical and mechanical specifications across all critical parameters. These parts are direct pin-for-pin and functional replacements suitable for applications requiring no design modification.

Functional Alternatives provide equivalent shift register functionality with modified electrical characteristics or package formats. These parts require design evaluation to confirm compatibility with existing circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: TPIC6C595D

The TPIC6C595D is the preferred substitute for the TPIC6C596D. This part maintains identical electrical specifications, package format, and pin configuration while offering Active product status. The TPIC6C595D provides long-term availability and supply chain stability, making it suitable for immediate design migration.

Secondary Recommendation: TPIC6C595DG4

The TPIC6C595DG4 provides parametric equivalence to the TPIC6C596D with identical electrical and mechanical characteristics. However, this part is Discontinued at DiGi Electronics, limiting its viability for new production designs. This option is suitable only for legacy system support or limited-quantity applications where existing inventory is available.

Alternative Consideration: TLC6C598QPWRQ1

The TLC6C598QPWRQ1 offers functional shift register capability with extended supply voltage range (3V to 5.5V) and integrated power switch functionality. This part requires package format change from 16-SOIC to 16-TSSOP and introduces different output characteristics (power switch versus open drain). The TLC6C598QPWRQ1 is suitable only for applications where the modified electrical characteristics and package format are compatible with existing circuit design. This part carries AEC-Q100 automotive qualification and Active product status.

Not Recommended: TPIC6C596DG4

The TPIC6C596DG4 is Obsolete and should not be selected for new designs or production planning.

Frequently Asked Questions (FAQ)

Q: Can TPIC6C595D be used as a direct replacement for TPIC6C596D?

A: Yes. The TPIC6C595D maintains identical electrical specifications, pin configuration, and 16-SOIC package format. No circuit modification is required for substitution.

Q: What is the difference between TPIC6C596D and TPIC6C595D?

A: Both parts are 8-bit shift registers with open-drain outputs, 4.5V to 5.5V supply voltage, and -40°C to 125°C operating temperature. The primary difference is product status: TPIC6C596D is Last Time Buy, while TPIC6C595D is Active with ongoing availability.

Q: Can TLC6C598QPWRQ1 replace TPIC6C596D in existing designs?

A: TLC6C598QPWRQ1 provides 8-bit shift register functionality but differs in output type (power switch versus open drain), package format (16-TSSOP versus 16-SOIC), and supply voltage range (3V to 5.5V versus 4.5V to 5.5V). Circuit redesign and validation are required before substitution.

Q: Why is TPIC6C596DG4 not recommended?

A: TPIC6C596DG4 is Obsolete and no longer in production. New designs should not depend on this part number.

Q: What are the package differences between substitute parts?

A: TPIC6C596D, TPIC6C595D, TPIC6C595DG4, and TPIC6C596DG4 all use 16-SOIC (0.154", 3.90mm Width) package. TLC6C598QPWRQ1 uses 16-TSSOP (0.173", 4.40mm Width) package, requiring PCB layout modification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance status.

Q: What is the moisture sensitivity level difference between substitutes?

A: TPIC6C596D, TPIC6C595D, TPIC6C595DG4, and TPIC6C596DG4 have MSL 1 (Unlimited). TLC6C598QPWRQ1 has MSL 3 (168 Hours), requiring controlled storage and handling procedures.
