74ALVC245WMX Equivalent & Substitute Parts

Part Overview

The 74ALVC245WMX is a non-inverting transceiver logic IC manufactured by onsemi, designed for 8-bit data bus applications with 3-state output capability. Operating across a supply voltage range of 1.65V to 3.6V, this component is classified as obsolete product status. Due to its obsolete designation, identifying functionally equivalent and parametrically compatible substitute parts is essential for design continuity and procurement flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74ALVC245WMX are classified based on strict adherence to the following electrical and mechanical parameters:

Primary Substitution 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)
• Mounting Type: Surface Mount
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Package Considerations:

• Direct substitutes maintain 20-SOIC (0.295", 7.50mm Width) package specification
• Similar substitutes utilize 20-SO (0.209", 5.30mm Width) package with identical electrical parameters
• Parametric equivalents may vary in packaging format (Tape & Reel, Bulk) while maintaining core electrical specifications

Series Variations:

• 74ALVC series parts are direct electrical equivalents
• 74ALVCH series parts are parametrically equivalent with identical electrical performance

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Identical Package): SN74ALVC245DW, SN74ALVC245DWR, SN74ALVCH245DW, and SN74ALVCH245DWR are direct substitutes maintaining the 20-SOIC (0.295", 7.50mm Width) package specification. All Texas Instruments variants carry Active product status and ROHS3 compliance, providing long-term availability and regulatory alignment.

Similar Substitutes (Package Variation): SN74ALVC245NSR utilizes a 20-SO (0.209", 5.30mm Width) package while maintaining all electrical parameters. This variant is suitable for applications where PCB footprint constraints permit the narrower package width.

Parametric Equivalents: 74ALVC245D,118 from NXP USA Inc. provides parametric equivalence with identical electrical specifications. This part is available in Bulk packaging and carries Active product status, offering alternative sourcing for high-volume applications.

All substitute parts maintain the core electrical specifications: 1.65V to 3.6V supply voltage, 24mA output current capability, 8-bit non-inverting transceiver configuration, and -40°C to 85°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVC245NSR replace 74ALVC245WMX in existing designs? A: SN74ALVC245NSR is electrically equivalent but uses a narrower 20-SO (0.209", 5.30mm Width) package versus the original 20-SOIC (0.295", 7.50mm Width). PCB footprint compatibility must be verified before substitution.

Q: What is the difference between 74ALVC and 74ALVCH series parts? A: Both series maintain identical electrical parameters including supply voltage (1.65V ~ 3.6V), output current (24mA), and operating temperature range (-40°C ~ 85°C). The 74ALVCH designation indicates a variant within the same functional family with equivalent performance characteristics.

Q: Are all substitute parts RoHS compliant? A: Texas Instruments variants (SN74ALVC245DW, SN74ALVC245DWR, SN74ALVCH245DW, SN74ALVCH245DWR, SN74ALVC245NSR) are ROHS3 compliant. The NXP part (74ALVC245D,118) does not specify RoHS status in the provided data.

Q: What packaging options are available for the 74ALVC245 base product? A: Substitute parts are available in multiple packaging formats: Tube (SN74ALVC245DW, SN74ALVCH245DW), Tape & Reel (SN74ALVC245NSR, SN74ALVC245DWR, SN74ALVCH245DWR), and Bulk (74ALVC245D,118).

Q: Is the 74ALVC245WMX still in production? A: No. The 74ALVC245WMX is classified as Obsolete. All listed substitute parts carry Active product status, ensuring continued availability and manufacturing support.

Q: What are the key electrical parameters that define substitutability? A: Substitutability is determined by: Logic Type (Transceiver, Non-Inverting), Number of Elements (1), Bits per Element (8), Output Type (3-State), Output Current (24mA), Supply Voltage Range (1.65V ~ 3.6V), Operating Temperature (-40°C ~ 85°C), and Moisture Sensitivity Level (MSL 1).
