The device contains one driver and one receiver in half duplex configuration. The ST1480A transmit and receive at guaranteed data rate at least to 12Mbps. All transmitter outputs and receiver inputs are protected to ±15kV using Human Body Model. Driver is short-circuit current limited and is protected against excessive power dissipation by thermal shutdown circuitry that place the driver outputs into a high-impedance state. The ST1480A input has a true fail-safe feature that guarantees a logic high output if both inputs are o……
