TLV3704IPW Equivalent & Substitute Parts

Part Overview

The TLV3704IPW is a general-purpose CMOS comparator IC manufactured by Texas Instruments, featuring four independent comparator elements in a 14-TSSOP surface-mount package. This device is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. The TLV3704IPW operates across a wide supply voltage range (2.7V to 16V single supply, ±1.35V to ±8V dual supply) with rail-to-rail output capability and low input offset voltage specifications suitable for precision analog signal comparison applications.

Substitute Part Grouping Explanation

Substitute parts for the TLV3704IPW are grouped based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

Number of comparator elements: 4 (mandatory match)
Output type: CMOS, Push-Pull, Rail-to-Rail capability
Supply voltage range: Must encompass or overlap with 2.7V ~ 16V single supply
Package type: 14-pin surface-mount variants (TSSOP or SOIC)
Operating temperature range: Must support -40°C ~ 125°C minimum
Input offset voltage: Maximum 5mV specification
Input bias current: Maximum 250pA specification

Grouping Logic:

Group 1 - Direct Replacement (Same Package, Active Status): TLV3704IPWR represents the active production equivalent with identical electrical specifications and 14-TSSOP packaging. This part maintains full compatibility with the obsolete TLV3704IPW.

Group 2 - Package Variant Substitutes (Different Package, Electrical Compatibility): MAX9024AUD+ and MAX9024AUD+T share the 14-TSSOP package but operate within a narrower supply voltage range (2.5V ~ 5.5V). These parts are suitable only for applications not requiring the extended voltage capability of the original part.

Group 3 - Cross-Manufacturer Alternatives (Different Package, Functional Equivalence): ALD4302ASBL (14-SOIC package) and MAX978ESE+ (16-SOIC package) provide four-element comparator functionality with different packaging and electrical characteristics. These require PCB layout modifications and are suitable only when supply voltage and operating temperature requirements align.

Engineering Selection Recommendations

Primary Recommendation: TLV3704IPWR

The TLV3704IPWR is the recommended substitute for the obsolete TLV3704IPW. This part maintains identical electrical specifications, supply voltage range (2.7V ~ 16V), operating temperature range (-40°C ~ 125°C), and 14-TSSOP packaging. The TLV3704IPWR is in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. No design modifications are required for this substitution.

Secondary Recommendation: MAX9024AUD+ or MAX9024AUD+T

These Analog Devices/Maxim parts provide four-element comparator functionality in the same 14-TSSOP package. However, the supply voltage range is restricted to 2.5V ~ 5.5V, making these suitable only for applications operating within this narrower voltage window. Both parts maintain active production status and ROHS3 compliance. The MAX9024AUD+T variant is supplied in Tape & Reel packaging, while MAX9024AUD+ is supplied in Tube packaging.

Tertiary Recommendation: ALD4302ASBL

The ALD4302ASBL from Advanced Linear Devices provides four-element comparator functionality but requires PCB layout modifications due to the 14-SOIC package format. The operating temperature range is limited to 0°C ~ 70°C, restricting use to commercial-grade applications. This part is suitable only when the narrower temperature range and different package footprint are acceptable.

Not Recommended: MAX978ESE+

The MAX978ESE+ operates with a 16-SOIC package requiring significant PCB redesign. The operating temperature range is limited to -40°C ~ 85°C, and quiescent current is substantially higher (650µA maximum) compared to the original specification (1µA maximum). This part should be considered only when package constraints and higher power consumption are acceptable trade-offs.

Frequently Asked Questions (FAQ)

Q: Can I use MAX9024AUD+ as a direct replacement for TLV3704IPW?

A: The MAX9024AUD+ shares the same 14-TSSOP package and provides four comparator elements. However, the supply voltage range is limited to 2.5V ~ 5.5V compared to the original 2.7V ~ 16V specification. Use this part only if your application operates exclusively within the 2.5V ~ 5.5V range.

Q: What is the key difference between TLV3704IPWR and TLV3704IPW?

A: The TLV3704IPWR is the active production equivalent of the obsolete TLV3704IPW. Electrical specifications and packaging are identical. The primary difference is product status: TLV3704IPW is obsolete while TLV3704IPWR is actively manufactured by Texas Instruments.

Q: Can I use ALD4302ASBL in place of TLV3704IPW without PCB modifications?

A: No. The ALD4302ASBL uses a 14-SOIC package while the TLV3704IPW uses 14-TSSOP. These packages have different pin configurations and footprints, requiring PCB layout changes. Additionally, the operating temperature range is limited to 0°C ~ 70°C.

Q: Which substitute part has the lowest quiescent current?

A: The TLV3704IPWR and ALD4302ASBL both specify 1µA maximum quiescent current, matching the original TLV3704IPW specification. The MAX9024AUD+ series specifies 5µA, while the MAX978ESE+ specifies 650µA.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (TLV3704IPWR, MAX9024AUD+, MAX9024AUD+T, ALD4302ASBL, and MAX978ESE+) are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What packaging options are available for the recommended substitute?

A: The TLV3704IPWR is available in Cut Tape (CT) and Digi-Reel packaging formats, providing flexibility for both manual assembly and automated production environments.

Q: Can I use MAX978ESE+ if my application requires extended temperature range?

A: No. The MAX978ESE+ operates only to 85°C maximum, which is below the original specification of 125°C. For applications requiring the full -40°C ~ 125°C temperature range, use TLV3704IPWR.
