74HC652DB,118 Equivalent & Substitute Parts

Part Overview

The 74HC652DB,118 is a non-inverting transceiver IC manufactured by NXP USA Inc., designed for 6V logic applications with 1 element and 8 bits per element configuration. This component features 3-state output capability and operates across a supply voltage range of 2V to 6V with an operating temperature range of -40°C to 125°C.

The 74HC652DB,118 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this transceiver architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74HC652DB,118 is determined by the following critical parameters:

• Base product number (74HC652 series architecture)
• Logic type (Non-Inverting Transceiver)
• Number of elements (1) and bits per element (8)
• Output type (3-State)
• Output current specifications (7.8mA, 7.8mA)
• Supply voltage range (2V ~ 6V)
• Operating temperature range compatibility
• Surface mount mounting type
• RoHS3 compliance

The SN74HC652DWR from Texas Instruments meets these core functional and electrical requirements. While package geometry differs (24-SOIC versus 24-SSOP), both are surface-mount packages with compatible pinout architecture for the 74HC652 base product. The operating temperature range of the substitute extends to 85°C maximum, which is narrower than the main part's 125°C specification.

Parameter Comparison

Engineering Selection Recommendations

The SN74HC652DWR qualifies as a functional substitute for the 74HC652DB,118 based on matching core electrical specifications, identical logic architecture, and equivalent compliance certifications. Both parts are ROHS3 compliant with MSL Level 1 ratings.

The primary design consideration is the operating temperature range differential. The 74HC652DB,118 supports operation to 125°C, while the SN74HC652DWR is rated to 85°C maximum. Applications requiring sustained operation above 85°C ambient temperature must retain the original NXP part or identify alternative solutions.

Package geometry differs between the two parts. The 74HC652DB,118 uses 24-SSOP packaging (5.30mm width), while the SN74HC652DWR uses 24-SOIC packaging (7.50mm width). PCB layout modifications are required for package substitution. Both packages maintain compatible pinout architecture for the 74HC652 base product series.

The SN74HC652DWR carries active product status, ensuring ongoing availability and supply chain support compared to the obsolete 74HC652DB,118.

Frequently Asked Questions (FAQ)

Q: Can the SN74HC652DWR directly replace the 74HC652DB,118 without PCB modifications?

A: No. While electrical specifications and pinout are compatible, the package geometries differ. The 74HC652DB,118 uses 24-SSOP (5.30mm width) and the SN74HC652DWR uses 24-SOIC (7.50mm width). PCB footprint redesign is required.

Q: What is the impact of the operating temperature range difference?

A: The 74HC652DB,118 operates to 125°C; the SN74HC652DWR operates to 85°C maximum. For applications operating above 85°C ambient temperature, the substitute is not suitable. Verify your system's thermal requirements before selection.

Q: Are both parts RoHS compliant?

A: Yes. Both the 74HC652DB,118 and SN74HC652DWR are ROHS3 compliant with MSL Level 1 moisture sensitivity ratings.

Q: Why is the 74HC652DB,118 listed as obsolete?

A: The 74HC652DB,118 has been discontinued by NXP USA Inc. The SN74HC652DWR from Texas Instruments remains in active production, providing continued availability for the 74HC652 transceiver architecture.

Q: Are the electrical output characteristics identical?

A: Yes. Both parts specify identical output current ratings of 7.8mA for high and low states, identical supply voltage range of 2V to 6V, and identical 3-state output configuration.
