Engineering Selection Recommendations

Primary Recommendation: LMV339M/NOPB

The LMV339M/NOPB from Texas Instruments is the direct equivalent of the LMV339M with identical electrical specifications and package configuration. This part maintains full functional compatibility while offering ROHS3 compliance and active product status, making it the preferred choice for design continuity and regulatory compliance.

Secondary Recommendation: LMV339DR2G (onsemi)

The LMV339DR2G provides the same 14-SOIC package and -40°C to 85°C operating range with ROHS3 compliance and active status. While output type differs (open-drain versus open-collector/TTL), this part is suitable for applications where open-drain output is acceptable. Input bias current is significantly lower (0.001µA versus 0.25µA), which may benefit low-power applications.

Alternative Recommendation: AS339AMTR-G1 (Diodes Incorporated)

The AS339AMTR-G1 maintains the 14-SOIC package and -40°C to 85°C operating range with superior input offset voltage (3mV versus 7mV). Extended supply voltage range (2V to 36V) provides greater design flexibility. Reduced quiescent current (2mA versus 300µA) and output current (16mA versus 84mA) require verification against application requirements.

Alternative Recommendation: BA2901F-E2 (Rohm Semiconductor)

The BA2901F-E2 offers extended operating temperature range (-40°C to 125°C) in a 14-SOIC package with ROHS3 compliance. Extended supply voltage range (2V to 36V) and lower quiescent current (2mA) support diverse application requirements. Input offset voltage matches the original specification at 7mV.

Package Variant Consideration: AS339GTR-E1 and AS339GTR-G1 (Diodes Incorporated)

These parts provide 14-TSSOP packaging as an alternative to 14-SOIC. Both maintain -40°C to 85°C operating range and ROHS3 compliance with extended supply voltage capability. PCB layout modifications are required to accommodate the different package footprint.

Through-Hole Alternative: NJM12901D1 (Nisshinbo Micro Devices Inc.)

The NJM12901D1 provides a 14-DIP through-hole package option for applications requiring through-hole mounting. Operating temperature range (-40°C to 85°C) and RoHS compliance are maintained. Supply voltage range is limited to 2V to 14V, requiring verification against application requirements.

Frequently Asked Questions (FAQ)

Q: Can LMV339M/NOPB be used as a direct replacement for LMV339M?

A: Yes. The LMV339M/NOPB is electrically and functionally identical to the LMV339M with identical specifications across all critical parameters: supply voltage (2.7V to 5.5V), input offset voltage (7mV @ 5V), input bias current (0.25µA @ 5V), output current (84mA @ 5V), and operating temperature range (-40°C to 85°C). The primary difference is ROHS3 compliance status and active product status. Package and pinout are identical.

Q: What are the key differences between LMV339M and AS339AMTR-G1?

A: Both parts provide four general-purpose comparators in compatible packages with -40°C to 85°C operating range. Key differences include: (1) Supply voltage range: LMV339M operates 2.7V to 5.5V, while AS339AMTR-G1 operates 2V to 36V; (2) Input offset voltage: LMV339M specifies 7mV @ 5V, AS339AMTR-G1 specifies 3mV @ 5V; (3) Output current: LMV339M provides 84mA @ 5V, AS339AMTR-G1 provides 16mA @ 5V; (4) Quiescent current: LMV339M draws 300µA maximum, AS339AMTR-G1 draws 2mA maximum. Applications requiring high output current or operating above 5.5V supply voltage should verify compatibility before substitution.

Q: Is the LMV339DR2G suitable as a substitute despite having open-drain output instead of open-collector?

A: Open-drain and open-collector outputs are functionally equivalent in most applications, both requiring external pull-up resistors for proper operation. The LMV339DR2G maintains the same 14-SOIC package, -40°C to 85°C operating range, and 84mA output current as the original LMV339M. However, input bias current is significantly lower (0.001µA versus 0.25µA), which may affect circuit behavior in applications with high-impedance input sources. Verification against specific application requirements is necessary.

Q: Can I use BA2901SFV-E2 in place of LMV339M if my PCB layout accommodates 14-LSSOP packaging?

A: Yes, if PCB layout modifications are acceptable. The BA2901SFV-E2 provides four general-purpose comparators with -40°C to 105°C operating range (exceeding the original -40°C to 85°C specification), ROHS3 compliance, and extended supply voltage range (2V to 36V). Input offset voltage (7mV @ 5V) and input bias current (0.25µA @ 5V) match the original specification. Quiescent current (2mA) and output current (16mA @ 5V) are lower than the original (300µA and 84mA respectively), requiring verification against application current requirements.

Q: What is the difference between AS339GTR-E1 and AS339GTR-G1?

A: Both parts are functionally identical quad comparators from Diodes Incorporated with identical electrical specifications: 14-TSSOP package, -40°C to 85°C operating range, 2V to 36V supply voltage, 5mV input offset voltage @ 5V, 0.25µA input bias current @ 5V, 16mA output current @ 5V, and 2mA quiescent current. The designation difference (E1 versus G1) reflects manufacturing date code or internal revision tracking. Both are ROHS3 compliant and active products. Selection between these parts should be based on availability and supplier preference.

Q: Why does LM339DT specify 0°C to 70°C operating temperature instead of -40°C to 85°C?

A: The LM339DT from STMicroelectronics is a different product variant with a narrower operating temperature range (0°C to 70°C) compared to the LMV339M (-40°C to 85°C). This part is suitable only for applications operating within the 0°C to 70°C range. Applications requiring -40°C to 85°C operation must select alternative parts such as LMV339M/NOPB, AS339AMTR-G1, or BA2901F-E2.

Q: Is NJM12901D1 compatible with surface-mount PCB designs?

A: No. The NJM12901D1 is a through-hole 14-DIP package device, requiring through-hole mounting on PCBs with appropriate via patterns. Surface-mount designs require selection of surface-mount alternatives such as LMV339M/NOPB (14-SOIC), AS339AMTR-G1 (14-SOIC), AS339GTR-E1 (14-TSSOP), or BA2901F-E2 (14-SOIC).

Q: What supply voltage range should I verify when substituting the LMV339M?

A: The original LMV339M operates across 2.7V to 5.5V supply voltage. Most substitute parts extend this range: AS339AMTR-G1, AS339GTR-E1, AS339GTR-G1, BA2901F-E2, and BA2901SFV-E2 all support 2V to 36V (or ±1V to ±18V dual supply). LM339DT supports 2V to 32V (or ±1V to ±16V dual supply). NJM12901D1 supports 2V to 14V. Applications operating at supply voltages below 2.7V or above 5.5V require selection of parts with extended voltage ratings. Verify that the substitute part's supply voltage range encompasses your application's operating requirements.
