74ALVC2245WMX Equivalent & Substitute Parts

Part Overview

The 74ALVC2245WMX is a non-inverting transceiver logic IC manufactured by onsemi, featuring 1 element with 8 bits per element and 3-state output capability. Designed for 1.65V to 3.6V supply voltage operation, this component operates across the -40°C to 85°C temperature range in a 20-SOIC surface mount package.

The 74ALVC2245WMX is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this transceiver architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74ALVC2245WMX are qualified based on the following criteria:

Core Functional 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)

Package Compatibility:

• Mounting Type: Surface Mount
• Package / Case: 20-SOIC or 20-SO (functionally equivalent pinouts)

All identified substitutes maintain identical electrical specifications and thermal operating ranges. Packaging variations (Tube, Tape & Reel, Bulk) represent distribution formats only and do not affect functional compatibility. Package case width variations (0.295" vs 0.209") indicate different physical footprints but maintain electrical equivalence within the 20-SOIC/20-SO family.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain electrical and thermal equivalence to the 74ALVC2245WMX. Selection should prioritize active product status for long-term supply chain stability.

Primary Substitutes (Active Status, Identical Package):

• SN74ALVC245DW (Texas Instruments, 20-SOIC, Tube packaging)
• SN74ALVC245DWR (Texas Instruments, 20-SOIC, Tape & Reel packaging)

These parts provide direct form-factor compatibility with the original 74ALVC2245WMX and maintain full electrical specification alignment.

Alternative Substitutes (Active Status, Package Variants):

• 74ALVC245D,118 (NXP USA Inc., 20-SO, Bulk packaging)
• SN74ALVC245NS (Texas Instruments, 20-SO)
• SN74ALVC245NSR (Texas Instruments, 20-SO, Tape & Reel packaging)

These parts utilize the 20-SO package format, which differs in physical footprint from the 20-SOIC but maintains electrical equivalence. PCB layout modification is required for implementation.

Series Variant Substitutes (Active Status, Enhanced Series):

• SN74ALVCH245DW (Texas Instruments, 74ALVCH series, 20-SOIC, Tube packaging)
• SN74ALVCH245DWR (Texas Instruments, 74ALVCH series, 20-SOIC, Tape & Reel packaging)

The 74ALVCH series represents an enhanced variant within the transceiver family, maintaining full electrical compatibility while offering extended product lifecycle support.

All substitute parts carry ROHS3 compliance and REACH unaffected status where specified, supporting regulatory requirements for modern manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVC245DW directly replace 74ALVC2245WMX without PCB modification?

A: Yes. Both parts use the 20-SOIC package format with identical pinout and electrical specifications. Direct substitution is possible without PCB layout changes.

Q: What is the difference between 20-SOIC and 20-SO packages?

A: Both are surface mount packages with identical electrical pinouts and functional compatibility. The primary difference is physical footprint dimensions. 20-SOIC typically has a 0.295" width, while 20-SO may have a 0.209" width. PCB footprint modification is required when switching between these package types.

Q: Are the 74ALVCH series parts (SN74ALVCH245DW, SN74ALVCH245DWR) fully compatible with the original 74ALVC2245WMX?

A: Yes. The 74ALVCH series maintains identical electrical specifications, voltage supply range, operating temperature range, and output current ratings. The series designation indicates an enhanced variant within the same functional family.

Q: Does packaging format (Tube, Tape & Reel, Bulk) affect electrical performance?

A: No. Packaging format represents distribution and handling method only. Electrical performance and specifications remain identical across all packaging formats for the same part number.

Q: Which substitute part offers the longest product lifecycle support?

A: All identified substitute parts carry active product status. Texas Instruments parts (SN74ALVC245DW, SN74ALVC245DWR, SN74ALVC245NS, SN74ALVC245NSR, SN74ALVCH245DW, SN74ALVCH245DWR) and NXP USA Inc. parts (74ALVC245D,118) are actively manufactured and supported.

Q: Are there compliance differences between substitute parts?

A: All substitute parts carry ROHS3 compliance and REACH unaffected status where specified. Moisture Sensitivity Level (MSL) is 1 (Unlimited) across all parts, indicating no moisture sensitivity constraints during storage or handling.
