SN74AS652DWRG4 Equivalent & Substitute Parts

Part Overview

The SN74AS652DWRG4 is a non-inverting transceiver IC manufactured by Texas Instruments, designed for 8-bit data transmission with 3-state output capability. Operating within a 4.5V to 5.5V supply voltage range, this component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs. The part is housed in a 24-SOIC surface mount package and complies with ROHS3 and REACH standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74AS652DWRG4 is determined by strict equivalence across the following critical parameters:

• Logic type and function: Non-inverting transceiver architecture
• Bit configuration: 1 element with 8 bits per element
• Output configuration: 3-state output capability
• Electrical specifications: 15mA output high current, 48mA output low current
• Supply voltage range: 4.5V to 5.5V
• Package form factor: 24-SOIC surface mount
• Compliance certifications: ROHS3 and REACH status

The SN74AS652DW meets all these criteria and serves as a direct functional equivalent. The primary distinction between the main part and its substitute is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The SN74AS652DW is the appropriate substitute for the obsolete SN74AS652DWRG4. Both parts maintain identical electrical and mechanical specifications, including supply voltage range, output current ratings, operating temperature range, and 24-SOIC package dimensions. The SN74AS652DW carries active product status from Texas Instruments, ensuring continued availability and manufacturing support. Both components satisfy ROHS3 compliance and REACH requirements, making them suitable for regulated applications. The only operational difference is packaging format: the main part uses reel packaging while the substitute uses tube packaging, which does not affect functional performance or PCB assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SN74AS652DW directly replace the SN74AS652DWRG4 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same 24-SOIC package footprint, pin configuration, and electrical characteristics. The difference in packaging format (reel versus tube) does not affect circuit performance or assembly compatibility.

Q: What is the significance of the product status difference?

A: The SN74AS652DWRG4 is classified as obsolete, indicating Texas Instruments no longer manufactures this variant. The SN74AS652DW maintains active status, ensuring continued production, availability, and technical support from the manufacturer.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the SN74AS652DWRG4 and SN74AS652DW are ROHS3 compliant and REACH unaffected, meeting the same regulatory requirements for industrial and commercial applications.

Q: Does the packaging format affect PCB assembly?

A: Packaging format (reel or tube) affects handling and storage procedures but does not impact PCB assembly, soldering, or functional performance. Both formats are compatible with standard surface mount assembly equipment.

Q: What are the critical parameters for confirming substitution compatibility?

A: Verify that the substitute maintains the same logic type (non-inverting transceiver), bit configuration (8 bits per element), output type (3-state), supply voltage range (4.5V to 5.5V), output current ratings (15mA high, 48mA low), and package form factor (24-SOIC). All these parameters are identical between the main part and substitute.
