Parameter Comparison

Engineering Selection Recommendations

The 74AVCH4T245BQ,115 is a direct functional equivalent to the 74AVC4T245RGYRG4 for translation transceiver applications requiring 3.6V logic level conversion. Both components meet ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards.

The substitute part offers improved availability through active product status and superior moisture handling characteristics (MSL 1 versus MSL 2). The package footprint difference (2.5x4.6mm versus 4x4.6mm) represents a physical size reduction while maintaining electrical compatibility and the same 16-pin VQFN configuration with exposed pad.

Selection between these components should be based on PCB layout constraints and supply chain availability. The substitute part is recommended for new designs and production continuity due to its active status and enhanced moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can the 74AVCH4T245BQ,115 directly replace the 74AVC4T245RGYRG4 in existing designs?

A: Yes, the 74AVCH4T245BQ,115 provides electrical equivalence across all functional parameters including element count, bit configuration, output type, current ratings, and supply voltage range. Both components operate identically within the -40°C to 85°C temperature range.

Q: What is the significance of the package size difference (4x4.6mm versus 2.5x4.6mm)?

A: The substitute part uses a more compact 16-DHVQFN package (2.5x4.6mm) compared to the original 16-VQFN (4x4.6mm). Both maintain the same pin count and electrical interface. PCB layout modifications may be required to accommodate the smaller footprint.

Q: Does the MSL rating difference affect component selection?

A: The substitute part has an MSL rating of 1 (Unlimited) compared to MSL 2 (1 Year) for the original. This indicates superior moisture resistance and more flexible storage and handling requirements, providing operational advantages without electrical impact.

Q: Are both components RoHS and REACH compliant?

A: Yes, both the 74AVC4T245RGYRG4 and 74AVCH4T245BQ,115 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why is the original part discontinued?

A: The 74AVC4T245RGYRG4 is discontinued at DiGi Electronics. The 74AVCH4T245BQ,115 remains in active production status, ensuring long-term availability for ongoing applications and future production runs.
