SCC2691AC1N24

NXP  SCC2691AC1N24  接口, UART, 1通道, 115.2 Kbaud, 4.5 V, 5.5 V, DIP, 24 引脚

The is an universal asynchronous Receiver/Transmitter with a single-chip CMOS-LSI communications device that provides a full-duplex asynchronous receiver/transmitter. It is fabricated with Philips semiconductors CMOS technology which combines the benefits of high density and low power consumption. The operating speed of the receiver and transmitter can be selected independently as one of 18 fixed baud rates, a 16X clock derived from a programmable counter/timer or an external 1X or 16X clock. The baud rate generator and counter/timer can operate directly from a crystal or from external clock inputs. The ability to independently program the operating speed of the receiver and transmitter make the UART particularly attractive for dual-speed channel applications such as clustered terminal systems.
