SN74LVTH543IPWREP Equivalent & Substitute Parts

Part Overview

The SN74LVTH543IPWREP is a non-inverting transceiver logic integrated circuit manufactured by Texas Instruments, classified within the 74LVTH series. This device functions as a single-element, 8-bit transceiver with 3-state output capability, designed for low-voltage applications operating between 2.7V and 3.6V. The part is currently in active production status with 1077 units available in new original inventory. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specification, enabling direct replacement in applications where the original part number becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SN74LVTH543IPWREP are identified based on strict parametric equivalence across the following critical criteria:

Electrical Parameters (Must Match):

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Current - Output High, Low: 32mA, 64mA
• Voltage - Supply: 2.7V ~ 3.6V
• Operating Temperature: -40°C ~ 85°C (TA)

Mechanical Parameters (Must Match):

• Package / Case: 24-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• Manufacturer: Texas Instruments
• Series: 74LVTH
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• Product Status: Active

All three substitute parts listed below meet these criteria and are therefore direct parametric equivalents suitable for component selection.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—SN74LVTH2952PWR, SN74LVTH543PWR, and SN74LVTH652PWR—are parametrically equivalent to the SN74LVTH543IPWREP and meet identical electrical, mechanical, and compliance specifications. Each part maintains active product status from Texas Instruments and carries ROHS3 compliance with MSL Level 1 rating.

Selection among these equivalents may be based on packaging format availability. The SN74LVTH543PWR is supplied in Cut Tape (CT) & Digi-Reel® format, while SN74LVTH2952PWR and SN74LVTH652PWR are supplied in Tape & Reel (TR) format. The original SN74LVTH543IPWREP is also supplied in Tape & Reel (TR) format. Inventory levels vary across all options, with SN74LVTH652PWR offering the highest stock availability at 3933 units.

Frequently Asked Questions (FAQ)

Q: Can SN74LVTH2952PWR, SN74LVTH543PWR, and SN74LVTH652PWR be used interchangeably with SN74LVTH543IPWREP?

A: Yes. All three parts are parametric equivalents meeting identical electrical specifications (2.7V ~ 3.6V supply, 32mA/64mA output current, -40°C ~ 85°C operating range), functional specifications (non-inverting transceiver, 1 element, 8 bits per element, 3-state output), and mechanical specifications (24-TSSOP package, surface mount). Direct substitution is supported.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® packaging provides components on cut tape segments, suitable for lower-volume or mixed-component assembly operations. Both formats contain identical components; the difference is in supply format only.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. SN74LVTH2952PWR, SN74LVTH543PWR, and SN74LVTH652PWR all carry ROHS3 compliance certification, matching the compliance status of SN74LVTH543IPWREP.

Q: What does Moisture Sensitivity Level (MSL) 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture exposure controls. Components with this rating do not require special moisture-barrier packaging or baking procedures prior to assembly, simplifying handling and storage requirements.

Q: Can I mix substitute parts within a single assembly?

A: Yes. Since all parts are parametrically equivalent with identical electrical and mechanical specifications, they can be used together in the same assembly without functional or compatibility concerns.
