ST485CDR Datasheet PDF - ST Microelectronics

●The ST485CDR is a Low Power Transceiver for RS-485 and RS-422 communication. This draw 300µA (typical) of supply current when unloaded or fully loaded with disabled drivers. Driver is short-circuit current limited and is protected against excessive power dissipation by thermal shutdown circuitry that placed the driver outputs into a high-impedance state. It is designed for bi-directional data communications on multipoint bus transmission line (half-duplex applications).

● -7 to 12V Common mode input voltage range

● Driver maintains high impedance in 3-state or with power OFF

● 70mV Typical input hysteresis

● 30ns Propagation delay, 5ns skew

● Operate from a single 5V supply

● Current limiting and thermal shutdown for driver overload protection

● Allows up to 64 transceivers on bus
