SN74ALVC245PW-P Equivalent & Substitute Parts

Part Overview

The SN74ALVC245PW-P is a non-inverting transceiver logic integrated circuit manufactured by Texas Instruments. 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 classified as Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when design requirements necessitate alternative packaging formats, inventory availability, or series variants while maintaining identical electrical and mechanical specifications. The substitute parts listed below satisfy all core functional parameters of the original SN74ALVC245PW-P.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SN74ALVC245PW-P are qualified based on strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• 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 Criteria:

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

Compliance Criteria:

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

Substitute parts differ only in series designation (74ALVC versus 74ALVCH) and packaging format (Tube or Tape & Reel versus Prototype designation). All substitutes maintain identical electrical performance and physical footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are qualified equivalents for the SN74ALVC245PW-P based on identical electrical specifications and mechanical compatibility. Selection among these parts is determined by packaging and supply chain requirements:

SN74ALVCH245PWR is supplied in Tape & Reel (TR) format, suitable for automated assembly processes and high-volume production environments. This packaging format provides 2200 units in current inventory.

SN74ALVC245PW is supplied in Tube packaging, appropriate for manual assembly or lower-volume applications. This variant maintains the 74ALVC series designation and provides 1644 units in inventory.

SN74ALVCH245PW is supplied in Tube packaging and utilizes the 74ALVCH series designation. This part provides 1175 units in current inventory.

All parts maintain Active product status and ROHS3 compliance. Selection should be based on production methodology, packaging requirements, and inventory availability rather than electrical performance, as all variants are electrically and mechanically equivalent.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVCH245PWR be used as a direct replacement for SN74ALVC245PW-P?

A: Yes. The SN74ALVCH245PWR is electrically and mechanically equivalent to the SN74ALVC245PW-P. Both devices feature identical logic type, bit configuration, output drive capability, supply voltage range, and operating temperature specifications. The primary difference is packaging format: SN74ALVCH245PWR is supplied in Tape & Reel format while SN74ALVC245PW-P is supplied in Prototype format. Both use the identical 20-TSSOP package footprint.

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

A: The provided data specifies that both series variants meet identical electrical and mechanical parameters for this product category. Series designation differences do not affect substitution eligibility when all other parameters are equivalent.

Q: Are there any compatibility issues when substituting between Tube and Tape & Reel packaging?

A: No compatibility issues exist at the component level. Tube and Tape & Reel packaging formats differ only in how units are supplied and handled during assembly. The physical component and electrical specifications remain identical. Selection between packaging formats depends on production equipment and assembly methodology.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All listed substitute parts, including SN74ALVC245PW-P, SN74ALVCH245PWR, SN74ALVC245PW, and SN74ALVCH245PW, have Moisture Sensitivity Level 1 (Unlimited). This indicates no special moisture handling precautions are required during storage or assembly.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All substitute parts use the identical 20-TSSOP package with 0.173" width and 4.40mm dimensions. PCB footprints, solder pad layouts, and pin assignments are identical across all variants, enabling direct substitution without design modification.

Q: What compliance certifications apply to all substitute parts?

A: All parts listed are ROHS3 compliant and carry identical environmental compliance status. REACH Status is listed as REACH Unaffected, ECCN as EAR99, and HTSUS as 8542.39.0001 for the substitute parts with complete compliance data.
