SN74BCT648NT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74BCT648NT is an octal bus transceiver and register manufactured by Texas Instruments. It belongs to the BCT logic series and features registered outputs with three-state capability. The device operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a 20-pin NT package designed for through-hole mounting. It supports TTL input levels and provides non-inverting data transfer between buses while latching the data internally.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity against manufacturer specifications due to obsolete status. Confirm package integrity and pin alignment prior to installation. Review current lifecycle documentation for availability constraints. Ensure design compatibility with existing system voltage requirements. Validate regulatory compliance markings on received units.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring simultaneous data latching and bidirectional bus driving. Consider the through-hole package constraint for PCB layout. Evaluate propagation delay characteristics against system timing requirements. Assess power consumption limits relative to available thermal dissipation capacity.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the SN74BCT family, which combines BiCMOS technology for high speed with standard logic compatibility. It serves as a registered version of basic bus transceivers, adding storage capability to prevent data loss during bus transitions. The NT suffix denotes the specific plastic dual in-line package variant.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include SN74BCT648DW and SN74BCT648DWR. Verify package type differences when substituting surface mount variants for through-hole designs.
