SCN2681A

High-performance Dual Universal Asynchronous Receiver/Transmitter (DUART) logic IC featuring two independent full-duplex communication channels and a quadruple-buffered receiver interface. | 40-Pin DIP or 44-Pin PLCC Package | Vintage multi-user Unix computers, clustered networking terminal systems, legacy automated industrial data-collection hubs. | SCN2681A | None | None | SCN2681AC1N40, SCN2681, SCC2681, MC2681, XR88C681 [1.31] | Modern Microcontroller Interface Expander: Wired into an active breadboard prototyping layout to serve as an asynchronous serial bridge, enabling a low-pin microcontroller (like an ESP32 or PIC) to cleanly drive two independent full-duplex hardware serial connections over long-distance RS-232 lines without losing timing data. | Signetics / Philips Data Communication Multi-Port Bus Controllers: This specialized communication semiconductor was engineered by Signetics to provide high-speed data format control and independent baud-rate selection routines within legacy networked terminals and multi-station computing platforms.
