Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation as Fairchild Semiconductor or ON Semiconductor, noting that Fairchild's semiconductor division was acquired by ON Semiconductor. Confirm the specific suffix 'MSA' corresponds to the required tape-and-reel packaging format and temperature grade. Ensure the component matches the 20-lead SOIC physical dimensions and pinout configuration before integration into the design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed signal buffering with strong drive current is required. The ABT logic family offers a balance between speed and power consumption suitable for 5V systems. Verify that the input voltage levels are compatible with the driving source, considering the Schmitt-trigger characteristics. Ensure the thermal management plan accommodates the package type and operating conditions.
