TLV3701IP Equivalent & Substitute Parts

Part Overview

The TLV3701IP is a general-purpose CMOS comparator with push-pull, rail-to-rail output configuration in 8-DIP through-hole packaging. This device operates across a wide supply voltage range (2.7V to 16V single supply, or ±1.35V to ±8V dual supply) and is designed for precision signal comparison applications. The TLV3701IP is currently in Last Time Buy status, making identification of active equivalent and substitute parts essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV3701IP is determined by the following critical parameters:

Functional Equivalence Criteria:

• Single general-purpose comparator element (Number of Elements = 1)
• CMOS output with push-pull, rail-to-rail configuration
• Supply voltage range compatibility (minimum 2.7V single supply or ±1.35V dual supply)
• Input offset voltage specification (5mV maximum)
• Input bias current specification (250pA maximum)
• Operating temperature range (-40°C to 125°C minimum)

Package and Mounting Considerations:

• Through-hole 8-DIP packaging is specific to the main part; surface-mount alternatives (SOT-23-5, 6-WLP, SC-70-5) represent functional equivalents with different form factors
• Substitution requires PCB redesign when transitioning between through-hole and surface-mount packages

Compliance Requirements:

• RoHS3 compliance maintained across all substitute parts
• REACH unaffected status consistent across all options

The substitute parts listed below meet the functional and electrical requirements for general-purpose comparator applications while offering different packaging options and product status classifications.

Engineering Selection Recommendations

TLV3701IDBVR (Texas Instruments, SOT-23-5)

This is the direct functional equivalent of the TLV3701IP from the same manufacturer. It maintains identical electrical specifications including supply voltage range (2.7V ~ 16V, ±1.35V ~ 8V), input offset voltage (5mV @ 15V), input bias current (250pA @ 15V), and CMRR/PSRR performance (88dB CMRR, 105dB PSRR). The TLV3701IDBVR is in Active product status with significantly higher inventory availability (36,900 pcs). The primary difference is packaging: SOT-23-5 surface-mount versus 8-DIP through-hole. Selection of this part requires PCB redesign for surface-mount implementation but provides long-term supply continuity.

MAX9027EBT+T (Analog Devices Inc./Maxim Integrated, 6-WLP)

This part operates within a narrower supply voltage range (1.8V ~ 5.5V) compared to the TLV3701IP. It provides superior input bias current performance (0.001µA @ 5V versus 250pA @ 15V) and higher output current capability (50mA typical). However, CMRR and PSRR performance are reduced (50.45dB CMRR, 60dB PSRR). Operating temperature range is limited to -40°C ~ 85°C. This part is suitable for low-voltage applications where the reduced supply range is acceptable and higher output current is beneficial.

MAX9075EXK+T (Analog Devices Inc./Maxim Integrated, SC-70-5)

This part offers the lowest input offset voltage (1mV @ 5V) among all substitutes and operates within 2.1V ~ 5.5V supply range. It provides good CMRR performance (82dB) but lower PSRR (77dB) compared to the TLV3701IP. Quiescent current is higher (6.6µA maximum). Operating temperature range is -40°C ~ 85°C. This part is appropriate for precision low-voltage comparator applications where minimal input offset is critical.

MAX9119EXK+T (Analog Devices Inc./Maxim Integrated, SC-70-5)

This part operates within 1.6V ~ 5.5V supply range with input offset voltage of 5mV @ 5V and superior input bias current (0.001µA @ 5V). Output current capability is 50mA typical. CMRR and PSRR are 66.02dB and 80dB respectively. Operating temperature range is -40°C ~ 85°C. This part is suitable for low-voltage applications requiring low input bias current and higher output drive capability.

All substitute parts maintain ROHS3 compliance and REACH unaffected status consistent with the main part.

Frequently Asked Questions (FAQ)

Q: Can the TLV3701IDBVR directly replace the TLV3701IP without circuit modifications?

A: The TLV3701IDBVR is electrically equivalent to the TLV3701IP and maintains identical functional specifications. However, it requires PCB redesign because it uses SOT-23-5 surface-mount packaging instead of 8-DIP through-hole packaging. Pin assignments differ between packages, necessitating layout changes.

Q: What is the primary reason the TLV3701IP is in Last Time Buy status?

A: The TLV3701IP is in Last Time Buy status, indicating Texas Instruments has discontinued this product line. The TLV3701IDBVR in SOT-23-5 packaging represents the active equivalent for new designs and ongoing production.

Q: Are the Maxim Integrated MAX90xx series parts direct substitutes for the TLV3701IP?

A: The MAX90xx series parts are functional equivalents for general-purpose comparator applications but operate within narrower supply voltage ranges (1.6V ~ 5.5V or 1.8V ~ 5.5V versus 2.7V ~ 16V for the TLV3701IP). They are suitable substitutes only for applications operating within their specified voltage ranges. All MAX90xx parts are limited to -40°C ~ 85°C operating temperature versus -40°C ~ 125°C for the TLV3701IP.

Q: Which substitute part offers the best performance match to the TLV3701IP?

A: The TLV3701IDBVR offers the closest performance match, maintaining identical electrical specifications and supply voltage range. It differs only in packaging format (SOT-23-5 surface-mount versus 8-DIP through-hole).

Q: Can I use a MAX90xx part in an application originally designed for the TLV3701IP operating at 12V supply?

A: No. The MAX90xx series parts are rated for maximum 5.5V supply voltage. Applications requiring supply voltages above 5.5V must use the TLV3701IDBVR or remain with the TLV3701IP if available from inventory.

Q: What are the key differences between the MAX9075EXK+T and MAX9119EXK+T?

A: Both parts use SC-70-5 packaging and operate within similar supply ranges (2.1V ~ 5.5V and 1.6V ~ 5.5V respectively). The MAX9075EXK+T offers lower input offset voltage (1mV @ 5V) but higher quiescent current (6.6µA). The MAX9119EXK+T provides lower input bias current (0.001µA @ 5V) and higher output current (50mA typical). Selection depends on whether precision offset voltage or low input bias current is the priority.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the TLV3701IP.
