Supports hardware automatic input/output toggle function (auto mode) and manually toggleable function (manual mode) according to input/output control signals.
The SB300 is a high-performance multi-protocol transceiver that supports RS232, RS422, and RS485 communication standards, featuring a compact QFN-40 package. The SB300 provides full RS232 signals (3TX, 5RX) and offers communication capabilities of up to 10 Mbps for RS422 (full duplex/4-wire) and RS485 (half duplex/2-wire). These are widely used in various fields in addition to RS232 communication. Furthermore, it supports slew rate limiting functions to minimize electromagnetic interference in EMI-sensitive environments. The SB300 provides a convenient automatic toggle function for RS422/485 communication and incorporates termination resistors internally, reducing the hassle of connecting external termination resistors. Additionally, it features an echo mode that allows the transmitted data to be received as is during RS485 data transmission, which is useful for testing purposes.
