Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging configuration, as indicated by the 'PWR' designation. Ensure compatibility with standard 20-TSSOP footprints during PCB layout. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated assemblies.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 5V-only supply system requires an octal transceiver with BCT speed characteristics. It is suitable for applications needing moderate propagation delays and standard drive currents. Consider alternative LVC or AX series devices if lower voltage operation or higher speed performance is required for the specific design constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74BCT family of high-speed CMOS logic devices. It serves as a variant of the SN74BCT245 logic gate, specifically packaged in a 20-pin Thin Shrink Small Outline Package (TSSOP) with a tape-and-reel orientation for automated assembly processes.
