Introduction
The HT3085 is low-power transceivers for RS-485-3.3 and RS-422-3.3 communication. IC contains one driver and one receiver. The driver slew rates of the HT3485 is not limited, allowing them to transmit up to 2.5Mbps. These transceivers draw between 120μA and 500μA of supply current when unloaded or fully loaded with disabled drivers. All parts operate from a single 3.3V supply. Drivers are short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit.
Features
- Low Quiescent Current: 300μA
- -7V to +12V Common-Mode Input Voltage Range
- Three-State Outputs
- 30ns Propagation Delays, 5ns Skew
- Full-Duplex and Half-Duplex Versions Available
- Operate from a Single 3.3V Supply
- Allows up to 32 Transceivers on the Bus
- Data rate: 2.5 Mbps
- Current-Limiting and Thermal Shutdown for Driver Overload Protection
- The transmitter outputs and receiver inputs are protected to ±15kV Air ESD
