TLV9024RTER Equivalent & Substitute Parts

Part Overview

The TLV9024RTER is a general-purpose comparator integrated circuit manufactured by Texas Instruments, housed in a 16-WQFN (3x3) surface-mount package. This device features four independent comparator elements with open-drain, rail-to-rail output configuration and operates across a supply voltage range of 1.65V to 5.5V. The TLV9024RTER maintains active product status and is available in tape and reel packaging format with 3,864 units in current inventory.

Equivalent and substitute parts are identified when alternative comparator devices meet the functional requirements of general-purpose signal comparison while maintaining compatibility with the electrical operating parameters and mechanical constraints of the application circuit. Substitution becomes necessary due to component availability, supply chain considerations, packaging preferences, or specific performance requirements within the allowed parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLV9024RTER are qualified based on the following substitution criteria:

Mandatory Compatibility Parameters:

• Four independent comparator elements
• General-purpose comparator classification
• Surface-mount technology
• Operating temperature range of -40°C to 125°C
• Supply voltage range overlap with 1.65V ~ 5.5V specification
• Active product status

Electrical Performance Allowances: Substitute devices must operate within the specified supply voltage range and maintain comparable input offset voltage, input bias current, and propagation delay characteristics. Output type configuration (open-drain or rail-to-rail) and quiescent current specifications are evaluated for application compatibility.

Package Considerations: While the primary package is 16-WQFN, substitute parts may utilize alternative surface-mount packages (such as 14-SOIC) provided the pin count and functional element count remain consistent at four comparators.

Parameter Comparison

Engineering Selection Recommendations

ADCMP393ARZ (Analog Devices Inc.): The ADCMP393ARZ is an active, general-purpose comparator with four elements in a 14-SOIC package. This device operates within the supply voltage range of 2.3V to 5.5V, which overlaps the upper portion of the TLV9024RTER specification. The ADCMP393ARZ features rail-to-rail output configuration and achieves ROHS3 compliance with MSL 1 rating. The propagation delay specification of 4.2µs is significantly longer than the TLV9024RTER, which may impact timing-critical applications. This substitute is suitable for applications where the minimum supply voltage requirement of 2.3V is acceptable and extended propagation delay does not affect circuit performance.

TS334IYDT (STMicroelectronics): The TS334IYDT is an active, general-purpose comparator with four elements in a 14-SOIC package. This device operates within the supply voltage range of 1.6V to 5V, providing near-complete overlap with the TLV9024RTER specification. The TS334IYDT features open-drain output configuration, matching the primary output type of the main part. The device achieves ROHS3 compliance, MSL 1 rating, and carries AEC-Q100 automotive qualification. The propagation delay specification of 210ns is within acceptable range for most general-purpose applications. This substitute provides the closest electrical and functional alignment with the TLV9024RTER.

Both substitute parts maintain active product status and are available in current inventory. Selection between substitutes depends on specific application requirements regarding supply voltage minimum threshold, propagation delay tolerance, and output configuration preference.

Frequently Asked Questions (FAQ)

Q: Can the ADCMP393ARZ replace the TLV9024RTER in all applications?

A: The ADCMP393ARZ operates with a minimum supply voltage of 2.3V, whereas the TLV9024RTER operates from 1.65V. Applications requiring operation below 2.3V cannot use the ADCMP393ARZ. Additionally, the ADCMP393ARZ propagation delay of 4.2µs is significantly longer than the TLV9024RTER specification of 100ns, which may affect timing-sensitive circuits.

Q: What are the package differences between the main part and substitutes?

A: The TLV9024RTER uses a 16-WQFN (3x3) package, while both substitute parts use a 14-SOIC package. The SOIC package has a larger footprint and different pin configuration. PCB layout modifications are required when substituting between these package types.

Q: Is the TS334IYDT suitable for low-voltage applications?

A: The TS334IYDT operates from 1.6V to 5V, making it suitable for applications requiring operation near the lower voltage limit. The TLV9024RTER operates from 1.65V, so the TS334IYDT provides comparable low-voltage performance with a 50mV lower minimum threshold.

Q: How do the output configurations differ between these parts?

A: The TLV9024RTER features open-drain, rail-to-rail output. The ADCMP393ARZ provides rail-to-rail output only. The TS334IYDT provides open-drain output only. Output configuration affects pull-up resistor requirements and maximum output voltage levels in the application circuit.

Q: What is the significance of the propagation delay differences?

A: The TLV9024RTER specifies 100ns maximum propagation delay, the TS334IYDT specifies 210ns, and the ADCMP393ARZ specifies 4.2µs. In high-frequency or timing-critical applications, the longer propagation delays of the substitutes may introduce unacceptable signal delays. Applications with relaxed timing requirements can tolerate these differences.

Q: Are there compliance or certification differences between these parts?

A: The ADCMP393ARZ and TS334IYDT both achieve ROHS3 compliance and carry MSL 1 ratings. The TS334IYDT additionally carries AEC-Q100 automotive qualification. The TLV9024RTER RoHS status is listed as not applicable. Applications requiring automotive-grade components should specify the TS334IYDT.

Q: Can these parts be used interchangeably on the same PCB?

A: No. The package differences (16-WQFN versus 14-SOIC) require different PCB footprints and cannot be used interchangeably without PCB redesign. Pin assignments and functional pinout must be verified before substitution.
