Engineering Selection Recommendations
Primary Substitutes (24-TSSOP Package Match)
The 74LVX3245MTCX from onsemi and 74LVXC3245MTCX from onsemi provide direct package compatibility with the original 74LVC4245APW,112. Both maintain the 24-TSSOP form factor, 8-channel bidirectional configuration, and tri-state output. The 74LVX3245MTCX carries active product status, ensuring long-term availability and supply chain stability. The 74LVXC3245MTCX is also active and represents an alternative within the same package footprint.
Secondary Substitutes (Alternative Packages)
The 74LVX4245MTCX from onsemi maintains the 24-TSSOP package and active status but differs in output designation (3-State versus Tri-State, Non-Inverted). The 74LVX3245QSCX from Fairchild Semiconductor uses a 24-SSOP package (0.154", 3.90mm width) rather than 24-TSSOP, requiring PCB layout verification for pin-to-pin compatibility.
Compact Package Alternatives (Analog Devices ADG3308 Series)
The ADG3308BRUZ-REEL from Analog Devices provides 20-TSSOP packaging with 8-channel bidirectional translation and active product status. This represents a more compact footprint than the original 24-TSSOP. The ADG3308BCBZ-1-RL7 and ADG3308BCPZ-REEL7 variants use 20-WLCSP and 20-LFCSP packages respectively, offering further miniaturization for space-constrained applications.
Texas Instruments LVCC Series
The CLVCC3245AIDBREP (24-SSOP) and CLVCC3245AIDWREP (24-SOIC) from Texas Instruments provide active product status with 8-channel bidirectional translation. Package differences require mechanical verification before selection.
All recommended substitutes maintain ROHS3 compliance, REACH unaffected status, and -40°C to 85°C operating temperature range consistent with the original specification.
Frequently Asked Questions (FAQ)
Q: Can I use a substitute part with a different package type?
A: Package substitution requires PCB layout verification. While electrical function may be equivalent, physical pin locations and footprints differ between 24-TSSOP, 24-SSOP, 24-SOIC, 20-TSSOP, 20-WLCSP, and 20-LFCSP packages. Direct board-level replacement is only possible with identical package types. Alternative packages require design modification.
Q: What is the difference between 74LVX and 74LVXC series translators?
A: Both series provide 8-channel bidirectional translation in compatible packages. The 74LVXC series supports a wider VCCB voltage range (3V to 5.5V) compared to standard 74LVX specifications. Series selection depends on specific voltage rail requirements in your application.
Q: Are all substitute parts ROHS3 compliant?
A: All listed substitute parts carry ROHS3 compliance certification. Compliance status is provided in the parameter comparison table. Verify specific certifications with your procurement documentation for regulatory requirements.
Q: Why is the original 74LVC4245APW,112 marked as obsolete?
A: Obsolete status indicates the manufacturer has discontinued production. Active substitute parts from onsemi, Fairchild Semiconductor, Analog Devices, and Texas Instruments provide equivalent functionality with ongoing manufacturing support and supply availability.
Q: Can I substitute a 20-channel ADG3308 for the 24-channel 74LVC4245?
A: The ADG3308 series provides 8-channel bidirectional translation identical to the 74LVC4245 channel count. The package designation (20-pin) refers to total pin count, not channel count. Electrical functionality is equivalent; package footprint differs and requires PCB layout adjustment.
Q: What operating temperature range applies to all substitutes?
A: All listed substitute parts operate across the -40°C to 85°C temperature range, matching the original 74LVC4245APW,112 specification. This range is suitable for industrial and commercial applications.
