SN74ALS652ANT Equivalent & Substitute Parts

Part Overview

The SN74ALS652ANT is a non-inverting transceiver IC manufactured by Texas Instruments, designed for 8-bit data transmission with 3-state output capability. This component operates within a 4.5V to 5.5V supply voltage range and is housed in a 24-pin DIP package for through-hole mounting applications.

The SN74ALS652ANT is classified as obsolete. Finding equivalent substitute parts is necessary to support legacy system maintenance, design updates, and procurement continuity when original stock becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74ALS652ANT is determined by functional equivalence across the following critical parameters:

• Logic type and transceiver configuration (non-inverting, single element, 8-bit per element)
• Output characteristics (3-state output capability)
• Electrical specifications (15mA/24mA output current, 4.5V–5.5V supply voltage)
• Operating temperature range (0°C–70°C)
• Base product number (74ALS652 series)
• Compliance certifications (ROHS3, REACH Unaffected, EAR99)

The SN74ALS652ADWR qualifies as a direct functional substitute. Both parts share identical logic functionality, electrical performance, and compliance status. The primary difference is packaging format: the original uses through-hole 24-DIP mounting, while the substitute uses surface-mount 24-SOIC packaging. This distinction requires design and assembly process consideration but does not affect electrical compatibility or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The SN74ALS652ADWR is the active-status equivalent for the obsolete SN74ALS652ANT. Both components maintain identical electrical specifications and regulatory compliance (ROHS3, REACH Unaffected, EAR99).

Selection between these parts depends on assembly methodology:

• Retain SN74ALS652ANT if through-hole mounting is required and legacy stock is available.
• Adopt SN74ALS652ADWR for new designs, system updates, or when surface-mount assembly is preferred. The active product status ensures long-term availability and supply chain continuity.

Both parts are functionally interchangeable from an electrical standpoint. PCB layout and assembly process modifications are necessary when transitioning from DIP to SOIC packaging.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALS652ADWR directly replace the SN74ALS652ANT in an existing circuit?

A: Electrically, yes. Both parts deliver identical logic functionality, output current ratings, and supply voltage specifications. However, the SOIC package requires surface-mount assembly, whereas the DIP package uses through-hole mounting. PCB redesign and assembly process changes are necessary for physical implementation.

Q: Why is the SN74ALS652ANT classified as obsolete?

A: The SN74ALS652ANT has reached end-of-life status with Texas Instruments. The SN74ALS652ADWR, in active production with identical electrical performance, is the recommended path for ongoing component sourcing.

Q: Are there differences in electrical performance between the two parts?

A: No. Both parts share identical specifications: 8-bit non-inverting transceiver configuration, 3-state output, 15mA/24mA output current, 4.5V–5.5V supply voltage, and 0°C–70°C operating temperature range.

Q: What is the primary difference between these two parts?

A: Packaging and mounting technology. The SN74ALS652ANT uses a 24-pin DIP package for through-hole mounting. The SN74ALS652ADWR uses a 24-pin SOIC package for surface-mount assembly. Electrical functionality remains identical.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Compliance certifications are equivalent.

Q: Which part should be selected for new designs?

A: The SN74ALS652ADWR is recommended for new designs. Active product status ensures availability, supply chain stability, and manufacturer support. Surface-mount technology also aligns with modern PCB assembly practices.
