TLC3704CPWRG4 Equivalent & Substitute Parts

Part Overview

The TLC3704CPWRG4 is a general-purpose CMOS comparator with four independent elements, designed for linear signal processing applications. Manufactured by Texas Instruments in the LinCMOS™ series, this device features push-pull and TTL-compatible outputs with a supply voltage range of 3V to 16V. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. The 14-TSSOP surface-mount package provides compact integration for modern PCB designs.

Substitute Part Grouping Explanation

Substitution for the TLC3704CPWRG4 is determined by the following critical parameters: four independent comparator elements, 14-TSSOP surface-mount package, input offset voltage of 5mV maximum, output current capability of 20mA typical, and operating temperature range of 0°C to 70°C.

The TLC3704CPWR from Texas Instruments is a parametric equivalent with identical electrical specifications and packaging, differentiated only by tape and reel packaging format rather than tube packaging.

The TS339CPT and TS339IPT from STMicroelectronics are manufacturer-recommended alternatives that maintain the four-element comparator architecture and 14-TSSOP package. These devices operate across an extended supply voltage range (2.7V ~ 16V single supply, ±1.35V ~ 8V dual supply) and feature open-drain output configuration instead of push-pull. The TS339IPT extends the operating temperature range to -40°C ~ 125°C, providing broader environmental compatibility.

Engineering Selection Recommendations

For direct replacement of the discontinued TLC3704CPWRG4, the TLC3704CPWR is the primary choice, offering identical electrical performance and packaging specifications with active product status and ROHS3 compliance.

The TS339CPT and TS339IPT from STMicroelectronics serve as cross-manufacturer alternatives. Both maintain ROHS3 compliance and the required 14-TSSOP package. The TS339IPT is recommended for applications requiring extended operating temperature range (-40°C to 125°C) and industrial environments. The TS339CPT is suitable for standard commercial temperature range applications (0°C to 70°C).

Output configuration differences must be evaluated: the TLC3704 series provides push-pull outputs, while the TS339 series provides open-drain outputs. Circuit designs utilizing pull-up resistors or open-drain compatible logic will accommodate the TS339 alternatives without modification. Designs dependent on push-pull output characteristics require the TLC3704CPWR.

All substitute options maintain REACH compliance and EAR99 export classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can the TS339CPT or TS339IPT directly replace the TLC3704CPWRG4 without circuit modification?

A: Direct pin-for-pin replacement is possible due to identical 14-TSSOP packaging and pinout. However, output configuration differs: TLC3704 provides push-pull outputs while TS339 provides open-drain outputs. Circuits designed for open-drain logic or incorporating pull-up resistors will function without modification. Circuits dependent on push-pull output drive capability require design review.

Q: What is the primary difference between TS339CPT and TS339IPT?

A: Both devices are electrically identical. The TS339IPT operates across an extended temperature range (-40°C to 125°C) compared to TS339CPT (0°C to 70°C). Selection depends on application environmental requirements.

Q: Why does the TLC3704CPWR show higher quiescent current than the TS339 alternatives?

A: The TLC3704CPWR specifies 100µA maximum quiescent current while TS339 devices specify 25µA maximum. This difference reflects design architecture variations between manufacturers. For power-sensitive applications, the TS339 series offers improved efficiency.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The TLC3704CPWR, TS339CPT, and TS339IPT all carry ROHS3 compliance certification, meeting environmental and regulatory requirements equivalent to the original TLC3704CPWRG4.

Q: What packaging formats are available for these comparators?

A: The TLC3704CPWRG4 is supplied in tube packaging. The TLC3704CPWR is available in tape and reel format. The TS339CPT is supplied in tape and reel format, while the TS339IPT is available in cut tape and Digi-Reel® format. Packaging selection depends on production volume and assembly requirements.
