Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity as the manufacturer was acquired by ON Semiconductor in September 2016. Confirm package type matches the 56-pin SSOP specification. Check for RoHS compliance status if required for specific manufacturing standards. Ensure the part number suffix corresponds to the correct variant, as availability may vary between original Fairchild stock and subsequent production runs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit registered transceiver with three-state outputs is required for bidirectional bus applications. It is suitable for designs needing independent direction control and high capacitive load driving. Consider the 56-pin SSOP package constraints and the 4.5V to 5.5V supply voltage range during circuit design. Verify compatibility with existing logic families and timing requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the 74ABT series of high-speed CMOS logic devices. Originally manufactured by Fairchild Semiconductor, production rights were transferred to ON Semiconductor following their acquisition in September 2016. The device serves as a registered bus transceiver, offering data latching functionality alongside standard transceiver operations for system synchronization.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Consider SN74ABT16543DL or SN74ABT16543DLR from Texas Instruments as parameter-equivalent substitutes. These alternatives offer similar 16-bit registered transceiver functionality and pinout compatibility. Verify electrical specifications and package dimensions before implementation.
