TLV2354IDRG4 Equivalent & Substitute Parts

Part Overview

The TLV2354IDRG4 is a LinCMOS™ differential comparator IC manufactured by Texas Instruments, featuring 4 differential elements in a 14-SOIC surface mount package. This device is designed for general-purpose voltage comparison applications with CMOS, MOS, open-drain, and TTL output configurations. The product is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2354IDRG4 is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 14-SOIC surface mount package to ensure direct PCB compatibility without layout modifications.

Functional Elements: The substitute must provide 4 differential comparator elements to maintain circuit functionality and pin-count equivalence.

Output Configuration: The substitute must support open-drain output type, which is the common functional output across both parts.

Supply Voltage Range: The substitute operating voltage must overlap with or encompass the 2V ~ 8V range of the original part. The LMV339DR2G operates at 2.7V ~ 5V, which covers the typical 5V operating point but has a narrower upper limit.

Electrical Performance: Input offset voltage, input bias current, and quiescent current specifications determine signal integrity and power consumption characteristics. These parameters must be within acceptable engineering tolerances for the application.

Compliance & Certifications: Both parts must maintain ROHS3 compliance and REACH unaffected status for regulatory continuity.

Parameter Comparison

Engineering Selection Recommendations

The LMV339DR2G is a direct functional substitute for the TLV2354IDRG4 based on the following criteria:

Package Equivalence: Both devices use the 14-SOIC surface mount package, enabling direct PCB replacement without layout redesign.

Functional Compatibility: Both parts provide 4 differential comparator elements with open-drain output configuration, maintaining circuit topology and signal processing capability.

Supply Voltage Consideration: The LMV339DR2G operates within the 2.7V ~ 5V range, which covers standard 5V applications. Applications requiring operation above 5V or below 2.7V require design review.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity for production and distribution.

Active Product Status: The LMV339DR2G is an active product with established supply chain availability, providing long-term sourcing reliability compared to the discontinued TLV2354IDRG4.

Performance Trade-offs: The LMV339DR2G exhibits higher input offset voltage (9mV vs. 5mV) and higher typical output current (84mA vs. 20mA), with lower quiescent current consumption (350µA vs. 800µA). These differences must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the LMV339DR2G directly replace the TLV2354IDRG4 on existing PCBs?

A: Yes. Both devices use the 14-SOIC package with identical pinout and footprint, enabling direct component substitution without PCB modifications.

Q: What are the key electrical differences between these parts?

A: The primary differences are input offset voltage (TLV2354IDRG4: 5mV vs. LMV339DR2G: 9mV), output current capability (TLV2354IDRG4: 20mA vs. LMV339DR2G: 84mA), and quiescent current (TLV2354IDRG4: 800µA vs. LMV339DR2G: 350µA). The LMV339DR2G also specifies a propagation delay of 1.5µs.

Q: Is the supply voltage range compatible?

A: The LMV339DR2G operates at 2.7V ~ 5V, which covers the 5V nominal operating point of the TLV2354IDRG4. Applications requiring operation above 5V or below 2.7V require circuit redesign or alternative component selection.

Q: Are both parts RoHS compliant?

A: Yes. Both the TLV2354IDRG4 and LMV339DR2G are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the moisture sensitivity level difference?

A: The TLV2354IDRG4 has MSL 1 (unlimited moisture exposure), while the LMV339DR2G has MSL 3 (168 hours). This affects storage and handling requirements; the LMV339DR2G requires more controlled moisture conditions during storage and assembly.

Q: Is the LMV339DR2G currently available?

A: Yes. The LMV339DR2G is an active product with 4424 pieces in stock, providing reliable supply chain availability for new designs and production continuity.
