Product Description

The DS485M is a low-power Multipoint Transceiver for RS-485 and RS-422 communication. The device contains one driver and one receiver. The driver slew rate allows for operation up to 2.5Mbps. The transceiver draws 200µA of supply current when unloaded or fully loaded with the driver disabled and operates from a single +5V supply. The driver is short-circuit current limited and is protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into tri-state (high impedance state) under fault conditions. The driver ensures a minimum of 1.5V differential output voltage with maximum loading across the common mode range (VOD3). The receiver has a failsafe feature that ensures a logic-high output if the input is open circuit.
Tri-state outputs on driver and receiver
Half-duplex flow-through pin-out
Allows up to 32 transceivers on the bus
Current-limiting and thermal shutdown for driver overload protection
Industrial temperature range operation
Pin and functional compatible with MAX485 and LTC485
-7 to +12V Common-mode input voltage range
25ns Typical driver transition time
40ns Typical driver propagation delay
1ns Typical driver skew
200ns Typical receiver propagation delay
20ns Typical receiver skew
