Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DW' confirms the SOIC-24 surface-mount package and commercial temperature grade (0°C to +70°C). Confirm RoHS compliance status through official manufacturer documentation, as environmental declarations may vary by production batch. Ensure the application circuit supports the specified 4.5 V to 5.5 V operating voltage range and TTL logic thresholds for reliable signal integrity.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal bus transceiver with internal registration is required for 5V logic systems. The BCT series offers BiCMOS technology for improved speed and drive capability compared to standard CMOS. Verify that the SOIC-24 package fits the PCB layout constraints and that the 0°C to +70°C operating range meets the environmental requirements of the target application.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the Texas Instruments SN74BCT family, which utilizes BiCMOS technology to combine the speed of bipolar devices with the low power consumption of CMOS. The 652 designation specifically indicates an octal bus transceiver with D-type flip-flop registers, distinguishing it from non-registered variants like the 653 or unidirectional buffers.
