TLC374CPWR Equivalent & Substitute Parts

Part Overview

The TLC374CPWR is a 4-channel differential comparator IC manufactured by Texas Instruments in the LinCMOS™ series. This surface-mount component operates across a supply voltage range of 3V to 16V (single supply) or ±1.5V to ±8V (dual supply), with an operating temperature range of 0°C to 70°C. The device features CMOS, MOS, and open-drain TTL output configurations, making it suitable for general-purpose analog comparison applications. As an active product with ROHS3 compliance and unlimited moisture sensitivity rating, the TLC374CPWR remains in production. Equivalent substitute parts are identified based on matching electrical parameters, package compatibility, and functional equivalence within the 4-channel comparator category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLC374CPWR are qualified based on the following electrical and mechanical criteria:

Matching Parameters:

• 4-channel comparator configuration (Number of Elements = 4)
• Open-drain output capability
• Supply voltage range compatibility (minimum 2.7V to 16V encompasses the TLC374CPWR range)
• Input offset voltage specification of 5mV or better
• Output current capability of 20mA or greater
• 14-TSSOP package footprint and surface-mount compatibility
• ROHS3 compliance and MSL Level 1 rating

Substitution Logic: The TS339CPT and TS339IPT are functionally equivalent general-purpose comparators manufactured by STMicroelectronics. Both devices maintain the same 4-element configuration, identical package geometry, and compatible electrical specifications. The primary differences are packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) and operating temperature range, with TS339IPT supporting extended temperature operation (-40°C to 125°C) compared to the standard range of TS339CPT (0°C to 70°C).

Parameter Comparison

Engineering Selection Recommendations

Both TS339CPT and TS339IPT are qualified substitutes for the TLC374CPWR based on functional equivalence and compliance certifications. Selection between these alternatives depends on application requirements:

TS339CPT (Tape & Reel packaging): Suitable for applications operating within the 0°C to 70°C temperature range. This variant matches the standard operating temperature specification of the TLC374CPWR and is appropriate for commercial and industrial environments with controlled thermal conditions.

TS339IPT (Cut Tape & Digi-Reel® packaging): Recommended for applications requiring extended temperature operation from -40°C to 125°C. This variant provides broader thermal coverage and is suitable for automotive, aerospace, and industrial applications subject to wider temperature extremes. The extended temperature rating does not compromise performance within the standard operating range.

Both substitutes demonstrate superior quiescent current characteristics (25µA maximum versus 800µA for the TLC374CPWR) and lower input bias current (1pA versus 5pA), representing improved power efficiency. All three devices maintain ROHS3 compliance and MSL Level 1 moisture sensitivity ratings, ensuring compatibility with modern manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can TS339CPT and TS339IPT be used interchangeably with TLC374CPWR?

A: Yes, both TS339 variants are functionally equivalent substitutes. The primary distinction is operating temperature range. TS339CPT operates 0°C to 70°C (matching TLC374CPWR), while TS339IPT extends to -40°C to 125°C. Selection depends on your application's thermal requirements.

Q: Are the package footprints identical?

A: Yes. All three devices use the 14-TSSOP package with 0.173" width and 4.40mm body dimension. PCB layouts and reflow profiles remain unchanged during substitution.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape suitable for high-volume automated assembly. Cut Tape & Digi-Reel® (CT) provides components on cut tape segments with optional reel packaging, offering flexibility for lower-volume or mixed-component orders. Electrical performance is identical; packaging format affects procurement and handling logistics only.

Q: Do the TS339 variants have better power consumption than the TLC374CPWR?

A: Yes. The TS339CPT and TS339IPT specify maximum quiescent current of 25µA compared to 800µA for the TLC374CPWR. This represents a 32-fold reduction in standby power consumption, beneficial for battery-powered or power-constrained applications.

Q: Are all three devices ROHS3 compliant?

A: Yes. The TLC374CPWR, TS339CPT, and TS339IPT all carry ROHS3 compliance certification and MSL Level 1 (unlimited) moisture sensitivity ratings, meeting modern environmental and manufacturing standards.

Q: Which substitute should I select for automotive applications?

A: TS339IPT is the appropriate choice for automotive environments due to its extended operating temperature range of -40°C to 125°C, which accommodates underhood and extreme climate conditions typical of automotive systems.
