Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix PGG indicates the TSSOP-20 package configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Check current product lifecycle status as components may transition to end-of-life phases. Ensure the operating voltage requirements align with the 2.3V to 3.6V specification before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional octal bus switching is required with low on-resistance. It serves as a direct pin-compatible replacement for standard '244 logic families. Consider its overvoltage tolerance and power-off isolation capabilities for robust system design. Verify that the supply voltage remains within the specified 2.3V to 3.6V range for optimal performance.
