TLC352IP Equivalent & Substitute Parts

Part Overview

The TLC352IP is a dual differential comparator IC manufactured by Texas Instruments, housed in an 8-pin DIP package for through-hole mounting. This device operates across a wide supply voltage range of 1.4V to 16V (single supply) or ±0.7V to ±8V (dual supply), making it suitable for analog signal comparison applications in industrial and consumer electronics. The TLC352IP is currently in Last Time Buy status, indicating limited availability. Finding equivalent substitute parts ensures design continuity and long-term supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC352IP is determined by electrical parameter equivalence and functional compatibility. The following criteria establish valid substitutes:

• Identical base product number (TLC352) ensuring core silicon functionality
• Matching differential comparator architecture with 2 elements
• Identical output type configuration (CMOS, MOS, Open-Drain, TTL)
• Identical supply voltage range (1.4V ~ 16V single, ±0.7V ~ ±8V dual)
• Matching input offset voltage specification (5mV @ 5V maximum)
• Matching input bias current specification (5pA @ 5V maximum)
• Identical output current capability (20mA typical)
• Identical quiescent current specification (400µA maximum)
• Identical operating temperature range (-40°C ~ 85°C)
• Equivalent RoHS and REACH compliance status

Package and mounting type differences do not affect electrical substitution eligibility, provided the application design accommodates the physical form factor change.

Engineering Selection Recommendations

The TLC352IDR (8-SOIC surface mount variant) is the direct electrical equivalent of the TLC352IP. Both devices share identical electrical specifications, supply voltage ranges, and performance characteristics within the LinCMOS™ series.

Selection between these variants depends on application requirements:

• TLC352IP (8-DIP through-hole) is appropriate for designs utilizing through-hole PCB assembly or breadboard prototyping
• TLC352IDR (8-SOIC surface mount) is appropriate for designs utilizing surface mount PCB assembly and offers higher inventory availability (17,117 units in stock versus 1,725 units for the DIP variant)

The TLC352IDR carries Active product status, ensuring continued manufacturer support and long-term availability, whereas the TLC352IP is in Last Time Buy status. Both devices maintain identical RoHS3 compliance and REACH Unaffected status, satisfying equivalent regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the TLC352IDR replace the TLC352IP in my design?

A: Yes, the TLC352IDR is electrically equivalent to the TLC352IP. Both devices have identical electrical specifications, supply voltage ranges, and performance characteristics. The primary difference is the package type: TLC352IP uses 8-DIP through-hole packaging, while TLC352IDR uses 8-SOIC surface mount packaging. Your PCB assembly process must accommodate the selected package type.

Q: What is the difference between 8-DIP and 8-SOIC packaging?

A: 8-DIP (Dual In-line Package) is a through-hole component with 0.300-inch lead spacing, suitable for through-hole PCB assembly. 8-SOIC (Small Outline Integrated Circuit) is a surface mount component with 0.154-inch width, suitable for surface mount PCB assembly. Pin configurations and electrical function are identical; only the physical form factor differs.

Q: Why is the TLC352IP in Last Time Buy status?

A: Last Time Buy status indicates that Texas Instruments is discontinuing this specific package variant. The TLC352IDR (8-SOIC) remains in Active status and is the recommended long-term alternative for new designs or production continuity.

Q: Are there any electrical performance differences between these parts?

A: No. Both the TLC352IP and TLC352IDR share identical electrical specifications, including supply voltage range (1.4V ~ 16V single, ±0.7V ~ ±8V dual), input offset voltage (5mV @ 5V maximum), input bias current (5pA @ 5V maximum), output current (20mA typical), and quiescent current (400µA maximum).

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TLC352IP and TLC352IDR are ROHS3 Compliant and REACH Unaffected, meeting equivalent regulatory requirements for industrial and consumer applications.
