Description
The SC28C94A1A is a quad universal asynchronous receiver/transmitter (UART) that combines four enhanced Philips Semiconductors industry-standard UARTs with an innovative interrupt scheme. It is implemented using Philips Semiconductors’ high-speed CMOS process and is designed for low power consumption. The SC28C94A1A allows for independent selection of operating speed for each receiver and transmitter, making it particularly attractive for dual-speed channel applications. With its small die size, cost-effectiveness, and various programmable features, the SC28C94A1A is suitable for a wide range of electronic applications.
