SN74LS592DR Equivalent & Substitute Parts

Part Overview

The SN74LS592DR is an 8-bit binary counter IC manufactured by Texas Instruments, housed in a 16-SOIC surface mount package. This component functions as a positive edge-triggered counter with a maximum count rate of 35 MHz and operates within a 4.75 V to 5.25 V supply voltage range. The SN74LS592DR is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution of the SN74LS592DR is determined by strict equivalence across the following parameters: logic type (binary counter), bit width (8-bit), counting direction (up), trigger mechanism (positive edge), count rate (35 MHz), supply voltage range (4.75 V ~ 5.25 V), operating temperature range (0°C ~ 70°C), and physical package specification (16-SOIC surface mount). The SN74LS592D meets all these criteria and is therefore a direct functional equivalent. Both parts share identical electrical characteristics, pin configuration, and mechanical form factor, enabling pin-for-pin replacement within the same PCB footprint.

Parameter Comparison

Engineering Selection Recommendations

The SN74LS592D is the recommended substitute for the obsolete SN74LS592DR. Both components are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications across all critical parameters. The SN74LS592D carries active product status, ensuring continued availability and supply chain reliability. Both parts meet ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements. The transition from SN74LS592DR to SN74LS592D requires no circuit modifications, PCB redesign, or firmware adjustments, as pin configuration and functional behavior remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the SN74LS592D directly replace the SN74LS592DR without PCB modifications?

A: Yes. Both parts are housed in the 16-SOIC package with identical pin assignments, electrical characteristics, and functional specifications. Direct pin-for-pin substitution is possible without PCB layout changes.

Q: What is the primary reason for substituting the SN74LS592DR?

A: The SN74LS592DR is classified as obsolete. The SN74LS592D is an active product from the same manufacturer with identical specifications, providing supply continuity and long-term availability.

Q: Are there any differences in compliance or regulatory status between these parts?

A: No. Both the SN74LS592DR and SN74LS592D are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: What are the critical parameters that define substitution eligibility for this 8-bit binary counter?

A: Substitution is determined by matching logic type (binary counter), bit width (8-bit), counting direction (up), trigger mechanism (positive edge), count rate (35 MHz), supply voltage (4.75 V ~ 5.25 V), operating temperature range (0°C ~ 70°C), and package type (16-SOIC surface mount).

Q: Is the SN74LS592D available in different packaging options?

A: The SN74LS592D is supplied in tube packaging. The physical package remains 16-SOIC (0.154", 3.90mm Width) for surface mount applications.
