SN74ALVC245PWR-P Equivalent & Substitute Parts

Part Overview

The SN74ALVC245PWR-P is a non-inverting transceiver logic integrated circuit manufactured by Texas Instruments, classified within the 74ALVC series. This device functions as a 1-element, 8-bit per element transceiver with 3-state output capability, housed in a 20-TSSOP surface mount package. The part is currently in active production status with 688 pieces available in new original inventory stock.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specification, enabling direct functional replacement in circuit applications. Substitution becomes necessary due to inventory availability, packaging format requirements, or supply chain considerations while maintaining identical electrical performance and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SN74ALVC245PWR-P are identified based on strict parameter equivalence across the following critical criteria:

Electrical Equivalence Parameters:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Current - Output High, Low: 24mA, 24mA
• Voltage - Supply: 1.65V ~ 3.6V
• Operating Temperature: -40°C ~ 85°C (TA)

Mechanical Equivalence Parameters:

• Mounting Type: Surface Mount
• Package / Case: 20-TSSOP (0.173", 4.40mm Width)
• Supplier Device Package: 20-TSSOP

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain identical electrical performance and mechanical compatibility. Differences exist only in packaging format (Tape & Reel versus Tube) and series designation (74ALVC versus 74ALVCH), which do not affect functional substitution capability.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status with Texas Instruments and comply with ROHS3 environmental standards. Selection among equivalent parts should be based on packaging format availability and inventory requirements:

SN74ALVCH245PWR (Tape & Reel format, 2200 pcs available): Suitable for high-volume production environments requiring automated component handling and tape-reel packaging.

SN74ALVC245PW (Tube format, 1644 pcs available): Suitable for standard manufacturing environments utilizing tube packaging for component distribution.

SN74ALVCH245PW (Tube format, 1175 pcs available): Suitable for standard manufacturing environments with tube packaging requirements.

All parts are ROHS3 compliant with MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. Electrical performance, thermal characteristics, and mechanical compatibility are identical across all substitute options.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVCH245PWR be used as a direct replacement for SN74ALVC245PWR-P?

A: Yes. Both parts are electrically and mechanically equivalent. The primary difference is packaging format (Tape & Reel versus PROTOTYPE designation). The 74ALVCH series designation indicates a variant within the same functional family with identical electrical specifications.

Q: What is the difference between 74ALVC and 74ALVCH series designations?

A: Both series maintain identical electrical parameters for this transceiver application, including supply voltage range (1.65V ~ 3.6V), output current (24mA), and operating temperature range (-40°C ~ 85°C). Series designation reflects internal design variants that do not affect functional substitution capability.

Q: Are all substitute parts available in the same 20-TSSOP package?

A: Yes. All substitute parts use the 20-TSSOP (0.173", 4.40mm Width) surface mount package, ensuring mechanical compatibility with existing PCB layouts and assembly processes.

Q: What packaging formats are available for these substitute parts?

A: Three packaging formats are available: Tape & Reel (SN74ALVCH245PWR), Tube (SN74ALVC245PW and SN74ALVCH245PW), and PROTOTYPE (SN74ALVC245PWR-P). Selection depends on manufacturing process requirements and component handling systems.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All parts are ROHS3 compliant with MSL rating of 1 (Unlimited). Compliance certifications are identical across all substitute options.

Q: Can these parts be used interchangeably in the same circuit design?

A: Yes. Electrical specifications, pin configuration, and mechanical dimensions are identical. Direct substitution is supported without circuit modification or design verification.
