Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix RSVR against the manufacturer datasheet to confirm the UQFN-16 package type and tape-and-reel orientation. Ensure that the ordering part number matches the exact pin configuration and electrical specifications required by the design. Cross-reference the RoHS compliance status and lead-free material declarations with the latest product change notifications provided by Texas Instruments before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits that require interfacing between 1.2-V and 3.6-V logic families. The AVCH series offers optimized performance for high-speed applications compared to standard AVC variants. Consider the UQFN-16 footprint constraints and thermal dissipation requirements during PCB layout. Verify that the system's maximum data rate does not exceed the specified 380 Mb/s limit under all operating conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74AVCH4T245 family of voltage-level translators. It shares functional similarities with other members like the SN74AVC4T245 but utilizes advanced CMOS technology for improved speed and lower power consumption. The RSVR suffix specifically denotes the surface-mount UQFN packaging variant designed for compact electronic assemblies.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include SN74AVCH4T245PWR (TSSOP-16) and SN74AVCH4T245PW (TSSOP-16). These alternatives offer identical electrical characteristics but differ in physical package dimensions. Verify pin-to-pin compatibility and thermal management requirements when transitioning between UQFN and TSSOP packages.
