Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'W' corresponds to the TSSOP-20 package and 'T' indicates tape-and-reel packaging configuration. Confirm the operating temperature range matches system requirements, as revisions may affect specifications. Ensure ESD precautions are followed during handling and installation to prevent damage to the CMOS inputs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for bus-oriented receivers and transmitters requiring high-density buffering. It is suitable for memory address drivers and clock drivers where 3-state control is necessary. Consider the wide voltage range and low input current for compatibility with various logic families. Verify thermal resistance values if operating near maximum temperature limits.
