Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CMSA' against the manufacturer's official datasheet to confirm the 20-SSOP package and 25-ohm resistor integration. Ensure the operating temperature range and voltage specifications align with your system requirements before procurement. Cross-reference the part number with ON Semiconductor documentation, as Fairchild Semiconductor products are now managed under this entity.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring octal buffering with integrated output termination. The 25-ohm resistors reduce reflections in high-speed traces. Compare performance metrics such as propagation delay and drive current against standard HC or HCT families if lower speed is acceptable. Ensure the 3.3V supply rail compatibility matches the target application voltage levels.

Buffers, Drivers, Receivers, Transceivers Part Context
