The DS36C278TM/NOPB from Texas Instruments is a low-power CMOS transceiver that meets the requirements of the RS-485 standard for multipoint data transmission and is also compatible with TIA/EIA-422-B. Its design offers significant power savings, making it suitable for battery-powered or power-conscious applications with a maximum ICC of 500 μA.
The transceiver features TRI-STATE capability on its driver and receiver outputs. The driver outputs can operate over a wide common mode range of -7V to +12V. Bus contention or fault situations that lead to excessive power dissipation are managed by an on-board thermal shutdown circuit, which forces the driver outputs into a high impedance state.
The receiver incorporates a fail-safe circuit that guarantees a high output state when the inputs are left open. This device is available in an 8-SOIC package and is fully specified for the industrial temperature range of -40°C to +85°C. It is a drop-in replacement for several other common transceivers, including the LTC485, MAX485, DS75176, and DS3695.
Key electrical characteristics include a supply voltage range of 4.75V to 5.25V, receiver hysteresis of 70 mV, and a unit load of ¼ (allowing for ≥12 nodes) or ½ (allowing for ≥64 nodes). ESD protection (Human Body Model) is rated at ≥2 kV.
