- National Semiconductor. Many interface chips and excellent application notes on a variety of topics. Also a source for the data sheet for the PC's 16550 UART.
- Texas Instruments has interface chips.
- Maxim Integrated Products has RS-232 and RS-485 chips of every variety. Also the 16-pin MAX3100 UART with SPI interface.
- Linear Technology is another good source for RS-232/485 chips.
- Intersil has RS-232 chips and the data sheet for the 6402 UART, which is an old, simple UART that's useful for basic monitoring and control applications.
