Not all manufacturers adopted this nomenclature, however, continuing to refer to the fixed chip as a To overcome these shortcomings, the series UARTs incorporated a byte FIFO buffer with a programmable interrupt trigger of 1, 4, 8, or 14 bytes. Exchange of the having only a one-byte received data buffer with aand occasionally patching or setting system software to be aware of the FIFO feature of the new chip, improved the reliability and stability of high-speed connections.

More critically, with only a 1-byte buffer there datashfet a genuine risk that a received byte will be overwritten if interrupt service delays occur. Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest.

Similarly numbered devices, with varying levels of compatibility with the original National Semiconductor part, are made by other manufacturers. National Semiconductor later released the A which corrected this issue.

The part was originally made by National Semiconductor. The A F version was a must-have to use modems with a data transmit rate of baud. The A and newer is pin compatible with the The original had a bug that prevented this FIFO from being used.
