Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DBR' corresponds to the SSOP-20 package and tape-and-reel orientation. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the operating temperature range meets system environmental constraints. Cross-reference the datasheet revision date to confirm technical accuracy before integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed performance and strong drive capability are required for octal bus applications. The BCT technology offers faster switching speeds compared to standard HCT or HC families while maintaining CMOS compatibility. Consider the 64 mA low-level output current for driving heavy capacitive loads or multiple downstream inputs effectively.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the difference between SN74BCT244 and SN74HCT244?

The SN74BCT244 utilizes BiCMOS technology offering significantly faster propagation delays and higher drive currents compared to the CMOS-based SN74HCT244.

Does the SN74BCT244DBR support bidirectional data flow?

No, it is a unidirectional buffer. For bidirectional applications, the SN74BCT245 series should be used instead.
