TLV2354IDR Equivalent & Substitute Parts

Part Overview

The TLV2354IDR is a LinCMOS™ differential comparator manufactured by Texas Instruments, designed for general-purpose signal comparison applications. This 4-element comparator IC features CMOS, MOS, open-drain, and TTL output configurations in a 14-SOIC surface-mount package. The device operates across a 2V to 8V supply voltage range and maintains an active product status with full RoHS3 compliance. Substitute parts are identified when equivalent functional performance can be achieved within the specified electrical and mechanical constraints of the application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV2354IDR is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 14-SOIC surface-mount package with identical physical dimensions (0.154", 3.90mm width) to ensure PCB footprint compatibility without redesign.

Functional Equivalence: The substitute must provide 4 differential comparator elements with open-drain output capability to maintain circuit functionality.

Electrical Operating Range: The substitute supply voltage range must encompass or overlap with the 2V to 8V specification of the TLV2354IDR. Input offset voltage and quiescent current specifications must remain within acceptable design margins.

Compliance & Certification: Both parts must maintain RoHS3 compliance and REACH unaffected status to satisfy regulatory requirements.

The LMV339DR2G from onsemi meets these substitution criteria within the defined electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (TLV2354IDR): Maintain use of the TLV2354IDR when the extended supply voltage range of 2V to 8V is required, particularly in applications operating above 5V. The lower input offset voltage (5mV) provides superior precision in threshold-sensitive comparator circuits. Active product status and unlimited moisture sensitivity level (MSL 1) support long-term availability and simplified handling requirements.

Substitute Selection (LMV339DR2G): The LMV339DR2G is suitable for applications constrained to the 2.7V to 5V supply range. This substitute offers reduced quiescent current (350µA vs. 800µA), beneficial for battery-powered or low-power designs. Higher output current capability (84mA vs. 20mA) accommodates applications requiring increased load-driving capacity. Both parts maintain active product status and full RoHS3 compliance, ensuring regulatory alignment and supply chain continuity.

Compliance Verification: Both parts are ROHS3 compliant and REACH unaffected, satisfying environmental and regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the LMV339DR2G directly replace the TLV2354IDR in all applications?

A: Direct substitution is valid only when the application operates within the 2.7V to 5V supply voltage range. Applications requiring operation above 5V or below 2.7V must retain the TLV2354IDR. The 14-SOIC package footprint is identical, eliminating PCB redesign requirements for compatible voltage applications.

Q: What is the impact of the higher input offset voltage in the LMV339DR2G?

A: The LMV339DR2G specifies a maximum input offset voltage of 9mV at 5V, compared to 5mV for the TLV2354IDR. This 4mV difference may affect threshold accuracy in precision comparator circuits. Applications with tight threshold tolerances should retain the TLV2354IDR or implement additional calibration circuitry when using the substitute.

Q: Are there differences in output drive capability between these parts?

A: Yes. The LMV339DR2G provides 84mA typical output current at 5V, while the TLV2354IDR provides 20mA typical output current. Applications requiring higher output current to drive external loads benefit from the LMV339DR2G. Conversely, applications with limited output current requirements perform identically with either part.

Q: Do both parts require identical PCB layout and handling procedures?

A: Both parts use the 14-SOIC surface-mount package with identical physical dimensions. PCB layout and soldering procedures are interchangeable. However, the LMV339DR2G specifies MSL 3 (168 hours) compared to MSL 1 (unlimited) for the TLV2354IDR, requiring stricter moisture control during storage and handling for the substitute part.

Q: Are both parts suitable for long-term production use?

A: Both parts maintain active product status with full RoHS3 compliance and REACH unaffected certification, supporting long-term production availability and regulatory compliance.
