Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific manufacturer designation, as this part number may be associated with Texas Instruments or IDT product lines rather than Renesas. Confirm RoHS compliance status and check for End-of-Life notifications before procurement. Ensure the TSSOP-56 package dimensions match your PCB footprint requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit registered transceiver with TTL compatibility is required. Consider the 5.2 ns propagation delay for timing constraints. Verify that the 48 mA low-level sink current meets the load requirements of the destination circuitry. Compare against the 74ACT16543 series if CMOS input levels are preferred over TTL.
