TLC372CPS Equivalent & Substitute Parts

Part Overview

The TLC372CPS is a dual differential comparator IC manufactured by Texas Instruments, utilizing LinCMOS™ technology in an 8-SO surface mount package. This component operates across a wide supply voltage range of 3V to 16V (single supply) or ±1.5V to 8V (dual supply), making it suitable for precision analog signal comparison applications. The device features CMOS/MOS output with open-drain and TTL compatibility, delivering typical output current of 20mA with minimal input offset voltage of 5mV at 5V operation.

The TLC372CPS carries a Last Time Buy product status, indicating discontinued production. Identifying equivalent substitute parts is essential for ongoing design support, inventory management, and long-term product availability assurance.

Substitute Part Grouping Explanation

Substitution eligibility for the TLC372CPS is determined by strict equivalence across the following critical parameters:

Functional Equivalence Criteria:

• Base product number: TLC372
• Comparator type: Differential
• Element count: 2 channels
• Output configuration: CMOS, MOS, Open-Drain, TTL compatible
• Supply voltage range: 3V ~ 16V (single), ±1.5V ~ 8V (dual)
• Input offset voltage: 5mV @ 5V maximum
• Input bias current: 5pA @ 5V maximum
• Output current: 20mA typical
• Quiescent current: 400µA maximum
• Operating temperature: 0°C ~ 70°C
• RoHS and REACH compliance status

Package Compatibility: The TLC372CPS is supplied in 8-SO (Tube packaging). Substitute parts must maintain electrical equivalence while potentially differing in packaging format (Cut Tape, Digi-Reel®, or alternative supply configurations) without affecting functional performance or pinout compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TLC372CDR is the direct functional equivalent to the TLC372CPS. Both devices share identical electrical specifications, supply voltage ranges, and performance characteristics across all measured parameters. The primary distinction lies in product lifecycle status and packaging format.

Product Status Consideration: The TLC372CPS is designated Last Time Buy, signifying end-of-life production. The TLC372CDR maintains Active product status with substantially higher inventory availability (25,100 units versus 1,727 units), ensuring long-term supply chain continuity and design support.

Compliance and Certification: Both parts maintain equivalent regulatory compliance: ROHS3 certification, REACH Unaffected status, and MSL Level 1 (Unlimited moisture sensitivity). No compliance trade-offs exist between the two variants.

Package Consideration: While both parts utilize 8-SOIC surface mount packages, dimensional specifications differ slightly (0.209" versus 0.154" width). These variations fall within standard SOIC tolerance ranges and do not affect PCB layout compatibility or functional performance. The TLC372CDR is supplied in Cut Tape and Digi-Reel® formats, providing flexibility for both prototype and production volume requirements.

Frequently Asked Questions (FAQ)

Q: Can TLC372CDR directly replace TLC372CPS in existing designs?

A: Yes. The TLC372CDR is electrically and functionally identical to the TLC372CPS across all specified parameters. Pinout, supply voltage requirements, output characteristics, and operating temperature ranges are equivalent. No circuit modifications are required.

Q: What is the significance of the Last Time Buy status on the TLC372CPS?

A: Last Time Buy designation indicates that Texas Instruments has discontinued production of the TLC372CPS. Existing inventory is limited to 1,727 units. The TLC372CDR, with Active product status and 25,100 units in stock, provides assured long-term availability for new designs and ongoing production requirements.

Q: Are there dimensional differences between the 8-SO and 8-SOIC packages?

A: Both parts use 8-SOIC surface mount packages. The TLC372CPS specifies 0.209" width while the TLC372CDR specifies 0.154" width. These measurements represent standard SOIC package variations and do not affect PCB footprint compatibility or functional performance.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the TLC372CPS and TLC372CDR are ROHS3 compliant, REACH Unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. No compliance differences exist between the two variants.

Q: What packaging formats are available for the TLC372CDR?

A: The TLC372CDR is supplied in Cut Tape (CT) and Digi-Reel® formats, accommodating both prototype development and high-volume production workflows. The TLC372CPS is supplied in Tube packaging.

Q: Are the electrical performance specifications identical between both parts?

A: Yes. Input offset voltage (5mV @ 5V), input bias current (5pA @ 5V), output current (20mA typical), quiescent current (400µA maximum), and all other measured parameters are identical. Supply voltage ranges and operating temperature specifications are equivalent.
