Part Overview

The TLV3704CPW is a general-purpose CMOS comparator IC with four independent elements, featuring push-pull, rail-to-rail output configuration in a 14-TSSOP surface-mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for new designs and production continuity. The TLV3704 series remains available in active variants with improved temperature ranges and packaging options, alongside compatible alternatives from other manufacturers that meet the core functional and electrical requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TLV3704CPW is determined by the following critical parameters:

Functional Equivalence: Four independent general-purpose comparator elements with CMOS output stage.

Electrical Compatibility: Supply voltage range, input offset voltage, input bias current, output current capability, and common-mode rejection ratio must support the intended application.

Package Compatibility: Surface-mount 14-pin packages (TSSOP, PDIP variants) with identical or compatible pinouts.

Operating Temperature Range: Extended temperature variants (TLV3704IPWR) support wider industrial ranges; through-hole alternatives (ALD4302 series) maintain the original 0°C ~ 70°C range.

Output Configuration: Rail-to-rail, push-pull output types ensure direct functional replacement in existing circuits.

Substitutes are grouped into three categories:

1. Direct TLV3704 Series Variants – Same base product, different packaging and temperature ratings
2. Pin-Compatible Through-Hole Alternatives – ALD4302 series with equivalent functionality but different package form factor
3. Functional Equivalents – MAX9024 and MAX978 series with comparable electrical performance in alternative packages

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Manufacturer, Same Package):

TLV3704IPWR is the active production equivalent of TLV3704CPW. Both use the 14-TSSOP surface-mount package and maintain identical electrical specifications. TLV3704IPWR extends the operating temperature range to -40°C ~ 125°C and is available in Cut Tape and Digi-Reel packaging, supporting both commercial and industrial applications. This is the preferred substitute for new designs requiring the TLV3704 series.

For Through-Hole PCB Designs:

ALD4302APBL and ALD4302PBL (Advanced Linear Devices) provide four-element general-purpose comparators in 14-DIP through-hole packages. These parts maintain the same functional output configuration and operating temperature range as the original TLV3704CPW. The ALD4302 series exhibits higher output current capability (60mA typical) compared to the TLV3704 (10mA typical), making them suitable for applications requiring greater drive capability. Input bias current is significantly lower (0.001µA vs. 250pA), and quiescent current is higher (1mA vs. 1µA). These trade-offs are acceptable for through-hole implementations where power consumption is less critical.

For Low-Voltage, High-Speed Applications:

MAX9024AUD+ and MAX9024AUD+T (Analog Devices/Maxim) operate within a narrower supply voltage range (2.5V ~ 5.5V) but deliver superior input offset voltage (1mV vs. 5mV) and faster propagation delay (8µs). These parts are suitable for 3.3V and 5V logic-level systems where precision and speed are prioritized. Extended temperature rating (-40°C ~ 125°C) supports industrial environments.

For Fastest Propagation Delay:

MAX978EEE+ and MAX978ESE+T (Analog Devices/Maxim) provide the fastest propagation delay (28ns) among all substitutes, with 16-pin packages (QSOP and SOIC respectively). These parts are optimized for high-speed signal conditioning applications. Operating temperature range extends to -40°C ~ 85°C. Higher quiescent current (650µA) reflects the performance trade-off.

Compliance and Certification:

All substitute parts carry ROHS3 compliance and REACH unaffected status, matching the original TLV3704CPW certification level. All parts are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Frequently Asked Questions (FAQ)

Q: Can TLV3704IPWR directly replace TLV3704CPW in existing designs?

A: Yes. TLV3704IPWR is the active production variant of the same base product (TLV3704). Both share identical pinout, package footprint (14-TSSOP), and electrical specifications. The primary difference is extended operating temperature range (-40°C ~ 125°C vs. 0°C ~ 70°C) and active product status. No circuit modifications are required.

Q: What is the key difference between surface-mount and through-hole substitutes?

A: Surface-mount substitutes (TLV3704IPWR, MAX9024, MAX978 series) use TSSOP, QSOP, or SOIC packages for automated assembly on modern PCBs. Through-hole substitutes (ALD4302 series) use 14-DIP packages for manual insertion or legacy PCB designs. Electrical functionality is equivalent; package selection depends on PCB assembly capability and design requirements.

Q: Are the ALD4302 parts fully compatible with TLV3704CPW?

A: ALD4302APBL and ALD4302PBL are functionally equivalent four-element comparators with compatible output configurations. Both maintain the 0°C ~ 70°C operating temperature range. Key differences include higher output current (60mA vs. 10mA), lower input bias current (0.001µA vs. 250pA), and higher quiescent current (1mA vs. 1µA). These differences do not prevent substitution in most applications; verify output current and power consumption requirements for your specific circuit.

Q: Why do MAX978 parts have higher quiescent current than other substitutes?

A: MAX978EEE+ and MAX978ESE+T achieve the fastest propagation delay (28ns) through higher internal bias current, resulting in 650µA quiescent current. This is a performance-versus-power-consumption trade-off. Select MAX978 parts only when propagation delay is a critical specification.

Q: Can I use MAX9024 parts in applications requiring the full 2.5V ~ 16V supply range of TLV3704CPW?

A: No. MAX9024AUD+ and MAX9024AUD+T operate within 2.5V ~ 5.5V supply range, which is narrower than the original TLV3704CPW (2.5V ~ 16V). Use MAX9024 parts only in 3.3V or 5V single-supply systems. For applications requiring higher supply voltages, retain TLV3704IPWR or evaluate ALD4302 series within their 4V ~ 10V range.

Q: What packaging options are available for production quantities?

A: TLV3704IPWR is supplied in Cut Tape (CT) and Digi-Reel packaging. MAX9024AUD+ is supplied in Tube; MAX9024AUD+T is supplied in Tape & Reel (TR). MAX978EEE+ is supplied in Tube; MAX978ESE+T is supplied in Tape & Reel (TR). ALD4302APBL and ALD4302PBL are supplied in Tube. Select packaging based on assembly equipment and volume requirements.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original TLV3704CPW. All parts are REACH unaffected and classified under ECCN EAR99.
