INS8250N-B

INS8250N-B: Universal Asynchronous Receiver/Transmitter (UART) Serial Communication Controller IC, representing an updated "B" revision design matrix of the standard programmable communications subsystem. It converts parallel internal data bytes into asynchronous serial transmission streams and vice versa, featuring on-chip baud rate generators, priority interrupt controls, and full modem lines to handle error-free RS-232 serial interfaces inside vintage microcomputers and terminals, housed in a standard 40-pin through-hole plastic dual in-line package (PDIP-40) layout.
