Présentation
Description
Key characteristics:
- Low power: Consumes 300µA (max) in shutdown mode.
- Wide supply range: Operates from 4.75V to 5.25V.
- Robust ESD protection: ±15kV (Human Body Model).
- Thermal shutdown: Prevents damage during faults.
The IC includes a driver and receiver, enabling bidirectional communication over long distances (up to 1200m at lower speeds). It is commonly used in industrial networks, automotive systems, and multipoint data transmission.
Packaged in an 8-pin PDIP, the LTC485CN8 is pin-compatible with industry-standard RS-485 transceivers like the SN75176.
For detailed specs, refer to the datasheet by Analog Devices (now part of Linear Technology).
Equivalent
- MAX485 (Maxim Integrated)
- SN65HVD72 (Texas Instruments)
- ADM485 (Analog Devices)
- SP485 (Sipex/Exar)
- DS485 (Maxim Integrated)
These chips offer similar functionality for RS485/RS422 communication, with variations in speed, power consumption, and additional features. Always check datasheets for exact compatibility.
Pinout
- Half-duplex communication.
- Driver (Tx) and receiver (Rx) with differential I/O (A, B for bus lines).
- Driver enable (DE) and receiver enable (RE) control pins.
- 5V single-supply operation.
- Up to 10Mbps data rate.
