INS8250N Universal Asynchronous Receiver-Transmitter DIP IC 40 Pin (Wide)

INS8250N Universal Asynchronous Receiver-Transmitter DIP IC 40 Pin (Wide)

The INS8250N is a Universal Asynchronous Receiver-Transmitter (UART) integrated circuit designed to handle serial communication between digital systems and external devices. It converts parallel data from a microprocessor into serial data for transmission and converts received serial data back into parallel form for processing. This IC became widely used in early computer systems, terminals, industrial controllers, and embedded applications requiring reliable asynchronous communication.

Housed in a 40-pin wide DIP package, the INS8250N provides programmable communication parameters such as baud rate, data bits, parity, and stop bits. It includes transmit and receive buffering, status registers, and interrupt support, making it suitable for interfacing with RS-232 drivers, modems, printers, terminals, and other serial peripherals. The device remains popular for retro-computing projects, industrial equipment maintenance, and educational applications involving UART communication.
