Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific revision and manufacturing status, as this part number may be obsolete or superseded by newer variants such as the SNR suffix versions. Confirm package integrity and RoHS compliance against the latest manufacturer datasheet before integration. Ensure the selected substitute maintains identical pinout and electrical characteristics if the original is unavailable.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver with TTL compatibility and high drive strength is required for 5V logic systems. Consider the DIP-20 package for through-hole mounting requirements. Evaluate the propagation delay and output current specifications against system timing and load constraints to ensure signal integrity in asynchronous bus architectures.

Buffers, Drivers, Receivers, Transceivers Part Context

The SN74BCT2245N belongs to the Texas Instruments BCT (Bipolar-CMOS Technology) series, which combines the speed of bipolar circuits with the low power consumption of CMOS. This series is widely used in digital systems requiring reliable bus interfacing. The N suffix denotes the DIP-20 plastic package format, distinguishing it from surface-mount alternatives like the DW or DWR variants.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes include the SN74BCT2245NSR. Verify that the replacement maintains the same DIP-20 package and electrical specifications if form-fit-function interchangeability is required.
