Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLV2354ID are identified based on strict electrical and mechanical compatibility criteria. The primary substitution logic is based on the following allowed parameters:

Critical Matching Parameters:

• Package type: 14-SOIC surface mount form factor
• Number of comparator elements: 4 channels
• Output configuration: Open-drain capability
• Supply voltage range: Minimum 2V operation
• Input offset voltage: Maximum 5mV specification
• Input bias current: Maximum 5pA specification
• Operating temperature range: -40°C to 85°C

Identified Substitute Parts:

1. TLV2354IDR (Texas Instruments) – Direct manufacturer replacement with identical electrical specifications and active product status
2. LMV339DR2G (onsemi) – Cross-manufacturer substitute with compatible 14-SOIC packaging and open-drain output configuration

Parameter Comparison

Engineering Selection Recommendations

TLV2354IDR (Primary Recommendation)

The TLV2354IDR is the manufacturer-recommended direct replacement for the obsolete TLV2354ID. Both devices share identical electrical specifications, including supply voltage range (2V ~ 8V), input offset voltage (5mV @ 5V), input bias current (5pA @ 5V), and quiescent current (800µA). The TLV2354IDR maintains active product status with ROHS3 compliance and MSL 1 rating, ensuring long-term availability and supply chain continuity. The primary distinction is packaging format: TLV2354IDR is supplied in Tape & Reel configuration versus the tube packaging of the obsolete TLV2354ID.

LMV339DR2G (Secondary Alternative)

The LMV339DR2G from onsemi provides functional equivalence through identical 14-SOIC packaging and open-drain output capability. This device operates within a narrower supply voltage range (2.7V ~ 5V) compared to the TLV2354ID (2V ~ 8V), which may limit applicability in designs requiring operation below 2.7V. The LMV339DR2G exhibits higher input offset voltage (9mV @ 5V versus 5mV @ 5V) and lower quiescent current (350µA versus 800µA). The device carries MSL 3 rating, requiring controlled moisture exposure during storage and handling. Selection of the LMV339DR2G is appropriate only when supply voltage constraints align with the 2.7V minimum specification and when the increased input offset voltage is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can TLV2354IDR be used as a direct replacement for TLV2354ID?

A: Yes. The TLV2354IDR is the manufacturer-recommended substitute with identical electrical specifications and 14-SOIC packaging. The primary difference is packaging format (Tape & Reel versus tube). Both devices are electrically interchangeable.

Q: What are the key differences between TLV2354IDR and LMV339DR2G?

A: The TLV2354IDR maintains the full 2V ~ 8V supply voltage range and 5mV input offset specification of the original TLV2354ID. The LMV339DR2G operates within a narrower 2.7V ~ 5V range with 9mV input offset voltage. Both share the 14-SOIC package and open-drain output configuration. Selection depends on specific supply voltage and precision requirements.

Q: Are all three devices pin-compatible?

A: Yes. The TLV2354ID, TLV2354IDR, and LMV339DR2G all utilize the 14-SOIC package with identical pinout, enabling direct PCB-level substitution without layout modifications.

Q: What is the impact of MSL rating differences?

A: The TLV2354ID and TLV2354IDR carry MSL 1 (Unlimited) ratings, allowing indefinite storage without moisture control. The LMV339DR2G carries MSL 3 (168 Hours), requiring controlled humidity storage and bake-out procedures before reflow soldering if moisture exposure limits are exceeded.

Q: Which substitute is recommended for new designs?

A: The TLV2354IDR is recommended for new designs as the active, manufacturer-supported replacement with identical specifications to the obsolete TLV2354ID. The LMV339DR2G is suitable only when supply voltage constraints (2.7V minimum) and increased input offset voltage (9mV) are compatible with application requirements.

Q: Are there supply voltage limitations when substituting with LMV339DR2G?

A: Yes. The LMV339DR2G minimum supply voltage is 2.7V, compared to 2V for the TLV2354ID and TLV2354IDR. Applications requiring operation below 2.7V must use the TLV2354IDR to maintain specification compliance.
