Microsemi Corporation's MAR8251CB is a CMOS Serial I/O Controller from the MAR8251 series. This component features two serial I/O channels, capable of asynchronous and bit-synchronous, byte-synchronous communication standards. It operates with a maximum data transfer rate of 0.0078125 Mbps and utilizes NRZ data encoding/decoding. The controller interfaces with an 8-bit external data bus and supports through-hole mounting in a 28-terminal CDIP package (R-CDIP-T28). Designed for robust operation, it offers a wide operating temperature range from -55°C to 125°C and a supply voltage range of 4.5V to 5.5V. The MAR8251CB is suitable for applications in aerospace, defense, and industrial automation where reliable serial communication is critical. This component adheres to stringent screening level standards including 38535Q/M, 38534H, and 883B.
