TLV3402CD Equivalent & Substitute Parts

Part Overview

The TLV3402CD is a dual-channel general-purpose comparator manufactured by Texas Instruments, featuring CMOS open-drain output architecture in an 8-SOIC surface-mount package. This device operates across a wide supply voltage range of 2.5V to 16V (single supply) or ±1.25V to ±8V (dual supply), making it suitable for analog signal comparison applications in industrial and consumer electronics.

The TLV3402CD is classified as obsolete, with limited inventory availability. Equivalent and substitute parts are necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements. Active alternatives with comparable or enhanced electrical characteristics are available from multiple manufacturers.

Engineering Selection Recommendations

Primary Recommendation: TLV3402IDR

The TLV3402IDR is the direct active equivalent from Texas Instruments. It maintains identical electrical specifications to the TLV3402CD with extended operating temperature range (-40°C to 125°C versus 0°C to 70°C) and active product status. The minimum supply voltage increases marginally from 2.5V to 2.7V, which is compatible with most applications. This part is available in Tape & Reel packaging and carries ROHS3 compliance with unlimited moisture sensitivity rating.

Secondary Recommendations: MAX992ESA+ / MAX992ESA+T

The MAX992 series from Analog Devices Inc./Maxim Integrated offers faster propagation delay (210ns versus 300µs) and superior input bias current performance (1pA versus 250pA). However, the maximum supply voltage is limited to 5.5V, restricting use in applications requiring higher voltage operation. These parts are active with extended temperature range (-40°C to 85°C) and ROHS3 compliance. MAX992ESA+T is available in Tape & Reel packaging for high-volume applications.

Alternative Consideration: MAX990ESA+ / MAX990ESA+T

The MAX990 series provides lower quiescent current (24µA versus 950nA) and extended temperature range. Propagation delay is slower (450ns) compared to the TLV3402CD. Supply voltage range is identical to MAX992 (2.5V to 5.5V). Suitable for low-power applications where supply voltage does not exceed 5.5V.

Microchip Alternative: MCP6567T-E/SN

The MCP6567T-E/SN offers the fastest propagation delay (80ns) and extended temperature range (-40°C to 125°C). Minimum supply voltage is reduced to 1.8V, enabling low-voltage applications. Maximum supply voltage is limited to 5.5V. Input offset voltage is higher (10mV) and quiescent current is elevated (130µA). Available in Cut Tape & Digi-Reel packaging with ROHS3 compliance and MSL-3 moisture sensitivity rating.

Advanced Linear Devices Options: ALD2303ASAL / ALD2303SAL

The ALD2303 series provides superior input offset voltage performance (1mV to 4mV) and extremely low input bias current (0.001µA). Supply voltage range is restricted to 3V to 10V (single supply) or ±1.5V to ±5V (dual supply). Operating temperature range matches the TLV3402CD (0°C to 70°C). Propagation delay and hysteresis specifications are not provided. These parts are suitable for precision analog applications within the specified voltage range.

Parametric Equivalent: TLV3401CD

The TLV3401CD is a single-channel variant with identical electrical specifications to the TLV3402CD. This part is classified as Last Time Buy and is not recommended for new designs. Use only when single-channel functionality is required and supply constraints prevent adoption of dual-channel alternatives.

Frequently Asked Questions (FAQ)

Q: Can TLV3402IDR directly replace TLV3402CD in existing designs?

A: Yes. The TLV3402IDR is the direct active equivalent with identical electrical specifications. The minimum supply voltage increases from 2.5V to 2.7V, which is compatible with standard applications. The extended operating temperature range (-40°C to 125°C) provides improved reliability. Packaging differs (Tape & Reel versus Tube), but the 8-SOIC footprint is identical.

Q: What is the primary limitation of MAX992ESA+ and MAX990ESA+ compared to TLV3402CD?

A: The maximum supply voltage is limited to 5.5V, compared to 16V for the TLV3402CD. These parts are suitable only for applications operating within the 2.5V to 5.5V range. If your design requires supply voltages above 5.5V, the TLV3402IDR or ALD2303 series are required.

Q: Why is propagation delay significantly different between substitute parts?

A: Propagation delay varies based on internal circuit architecture and manufacturing process. The TLV3402CD specifies 300µs maximum delay, while the MAX992 series achieves 210ns and the MCP6567 achieves 80ns. Faster propagation delay improves response time in high-speed comparison applications but may increase power consumption. Select based on application timing requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification. The TLV3402CD also meets ROHS3 requirements. Moisture sensitivity levels vary: TLV3402CD, TLV3402IDR, MAX992, MAX990, and ALD2303 series carry MSL-1 (unlimited); MCP6567T-E/SN carries MSL-3 (168 hours).

Q: Can I use TLV3401CD (single-channel) as a substitute for TLV3402CD (dual-channel)?

A: No. The TLV3401CD is a single-channel comparator, while the TLV3402CD contains two independent comparators. Using a single-channel part requires circuit redesign. The TLV3401CD is classified as Last Time Buy and is not recommended for new designs.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is used for manual assembly and small-volume applications. Tape & Reel packaging is used for automated pick-and-place assembly in high-volume production. Both formats contain identical die and electrical specifications. Select based on manufacturing process requirements.

Q: Which substitute offers the best input offset voltage performance?

A: The ALD2303ASAL offers the lowest input offset voltage at 1mV @ 5V, compared to 3.6mV for the TLV3402CD. However, the ALD2303 series is limited to 10V maximum supply voltage. For applications requiring both low offset voltage and high supply voltage capability, the TLV3402IDR is recommended.

Q: Is the MCP6567T-E/SN suitable for high-speed applications?

A: Yes. The MCP6567T-E/SN offers the fastest propagation delay (80ns) among all listed substitutes. However, it carries MSL-3 moisture sensitivity rating (168-hour floor life) compared to MSL-1 for other parts. Extended temperature range (-40°C to 125°C) supports demanding environments. Supply voltage is limited to 5.5V maximum.
