SN74LVTH240IPWREP Equivalent & Substitute Parts

Part Overview

The SN74LVTH240IPWREP is a logic buffer IC with inverting functionality, designed for 3-state output applications in low-voltage environments. Manufactured by Texas Instruments, this 20-TSSOP surface mount device operates across a 2.7V to 3.6V supply range and is rated for -40°C to 85°C operating temperatures. The product is currently classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the SN74LVTH240IPWREP is determined by strict parametric equivalence across the following criteria:

Critical Matching Parameters:

Logic Type: Buffer, Inverting (2 Element, 4 Bit per Element)
Output Type: 3-State
Current Ratings: 32mA (Output High), 64mA (Output Low)
Voltage Supply Range: 2.7V ~ 3.6V
Operating Temperature Range: -40°C ~ 85°C
Package: 20-TSSOP with identical physical dimensions
Mounting Type: Surface Mount

All identified substitute parts maintain identical electrical specifications and physical packaging, ensuring direct functional replacement without circuit redesign. Substitutes are grouped by manufacturer and product status to facilitate procurement decisions.

Engineering Selection Recommendations

Active Product Status Preference: SN74LVTH240PWR and SN74LVT240APWR are recommended as primary substitutes due to active product status with Texas Instruments, ensuring long-term availability and manufacturing support. Both maintain identical electrical and mechanical specifications to the obsolete SN74LVTH240IPWREP.

Alternative Sourcing: 74LVT240PW,118 (NXP USA Inc.) and 74LVT240PW/AUJ (NXP Semiconductors) provide additional sourcing options with active status. The NXP variants offer higher inventory availability (7937 and 708 units respectively) for immediate procurement needs.

Last Time Buy Consideration: 74LVTH240MTCX from onsemi carries Last Time Buy status, indicating limited future availability. This part is suitable for current projects but not recommended for long-term production planning.

Compliance Alignment: All recommended substitutes maintain ROHS3 compliance and MSL Level 1 ratings, matching the original part's environmental and regulatory certifications. REACH and ECCN classifications remain consistent across all equivalents.

Frequently Asked Questions (FAQ)

Q: Can SN74LVT240APWR directly replace SN74LVTH240IPWREP? A: Yes. Both parts share identical electrical specifications (2.7V–3.6V supply, 32mA/64mA output current, -40°C to 85°C operating range) and 20-TSSOP packaging. The primary difference is series designation (74LVT vs. 74LVTH) and active product status, with no functional impact on circuit performance.

Q: What is the difference between 74LVTH and 74LVT series designations? A: Series designation reflects internal design generation and manufacturer product line organization. For the SN74LVTH240IPWREP application, both 74LVTH and 74LVT variants meet identical parametric requirements and are functionally interchangeable.

Q: Are NXP parts compatible with Texas Instruments designs? A: Yes. The 74LVT240PW,118 and 74LVT240PW/AUJ variants from NXP maintain identical electrical specifications, output characteristics, and 20-TSSOP packaging. Cross-manufacturer substitution is valid based on parametric equivalence.

Q: Does packaging format (Tape & Reel vs. Bulk vs. Cut Tape) affect electrical performance? A: No. Packaging format affects only handling, storage, and procurement logistics. Electrical and mechanical specifications remain identical regardless of packaging presentation. Selection should be based on assembly process requirements and inventory management practices.

Q: Why is SN74LVTH240IPWREP classified as obsolete? A: Obsolete status indicates Texas Instruments has discontinued active manufacturing and support. Active equivalents (SN74LVTH240PWR, SN74LVT240APWR) provide identical functionality with ongoing manufacturer support and availability assurance.

Q: Can I use 74LVTH240MTCX for new production designs? A: The 74LVTH240MTCX is suitable for current projects but carries Last Time Buy status, indicating limited future manufacturing. For new production designs requiring long-term component availability, SN74LVTH240PWR or SN74LVT240APWR are preferred.
