Substitute Part Grouping Explanation
Substitution of the SN74LS652NT is determined by strict equivalence across the following electrical and mechanical parameters:
- Logic type: Transceiver, Non-Inverting
- Number of elements: 1
- Number of bits per element: 8
- Output type: 3-State
- Current specifications: 15mA (output high), 24mA (output low)
- Supply voltage range: 4.75V ~ 5.25V
- Operating temperature range: 0°C ~ 70°C
- Series classification: 74LS
- Base product number: 74LS652
The SN74LS652DW qualifies as a direct functional substitute based on identical electrical characteristics and series designation. The primary difference is packaging format: the substitute uses surface-mount 24-SOIC technology instead of through-hole 24-DIP, requiring PCB layout and assembly process modifications.

Engineering Selection Recommendations
The SN74LS652DW is the manufacturer-recommended substitute for the obsolete SN74LS652NT. Both components maintain identical electrical performance specifications and comply with ROHS3 and REACH requirements. The SN74LS652DW carries active product status, ensuring continued availability and manufacturing support.
Selection between these parts depends on PCB design constraints. The SN74LS652NT requires through-hole mounting and is suitable for legacy board designs or applications where through-hole assembly is specified. The SN74LS652DW requires surface-mount assembly and is appropriate for new designs or board revisions utilizing modern manufacturing processes.
Both components are ROHS3 compliant with unlimited moisture sensitivity classification, indicating no special handling requirements during storage or assembly.
Frequently Asked Questions (FAQ)
Q: Can the SN74LS652DW directly replace the SN74LS652NT in an existing circuit?
A: Electrical substitution is direct. The components are functionally identical in logic operation, output characteristics, and electrical performance. However, physical substitution requires PCB redesign due to different package formats: the original uses 24-DIP through-hole mounting while the substitute uses 24-SOIC surface-mount technology.
Q: What are the key differences between these parts?
A: The primary differences are mounting type and package format. The SN74LS652NT uses through-hole 24-DIP packaging (0.300" pitch), while the SN74LS652DW uses surface-mount 24-SOIC packaging (0.295" width). All electrical parameters, including supply voltage, output current, and operating temperature range, are identical.
Q: Why is the SN74LS652NT classified as obsolete?
A: The SN74LS652NT is obsolete due to industry transition from through-hole to surface-mount assembly technology. The SN74LS652DW represents the current-generation equivalent in surface-mount format.
Q: Are there any compliance or certification differences?
A: Both components are ROHS3 compliant and REACH unaffected. Moisture sensitivity levels are identical at MSL 1 (Unlimited), requiring no special handling precautions.
Q: What supply voltage range do these components support?
A: Both the SN74LS652NT and SN74LS652DW operate within 4.75V to 5.25V supply voltage range, suitable for standard 5V logic systems.
Q: What is the output current capability?
A: Both components provide 15mA output high current and 24mA output low current, with 3-state output configuration for bus-oriented applications.
