Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer origin carefully, as IDT was acquired by Renesas Electronics. Confirm that the specific NBCTPA suffix corresponds to the SSOP package variant. Ensure compatibility with existing design specifications regarding pinout and electrical characteristics before procurement, as legacy components may have limited availability or require cross-referencing with updated Renesas part numbers.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit width is required for latched bus applications. It is suitable for designs needing registered outputs to isolate source from load. Compare against other FCT series devices if lower pin counts or different packaging options are preferred. Verify that the operating temperature range meets the environmental requirements of the target application.
