Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer origin carefully, as Harris Semiconductor assets were acquired by Texas Instruments. Confirm that the specific part number corresponds to the original Harris production run rather than subsequent TI manufacturing. Ensure the component matches the specified 48-pin PDSO physical form factor and FCT logic family characteristics during inspection.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a four-channel, four-bit buffer with true output polarity is required. It is appropriate for designs needing 3-state control and operation at standard 5 V logic levels. Consider the 4.1 ns propagation delay and 50 pF load capability against system timing requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Harris FCT (Fast CMOS) logic family, designed for high-speed digital applications. It serves as a buffer or line driver within this series, distinct from transceivers or latches. The FCT line was engineered to offer performance comparable to older TTL technologies while utilizing modern CMOS power efficiency.
