The LTC1481IS8#PBF is a high-performance, low power RS485 transceiver from Linear Technology, designed to facilitate robust serial communication in harsh industrial environments. This device is part of a family of transceivers that provide differential bus communication capability which conforms to both the RS485 and RS422 standards, making it versatile for a variety of network applications.
With an operating voltage range from 4.75V to 5.25V, the LTC1481IS8#PBF is optimized for low power consumption, drawing only 1.5mA of supply current when unloaded or fully loaded with the driver disabled. This makes it an excellent choice for power-sensitive applications. In addition, the receiver has a fail-safe feature that guarantees a high output state if the inputs are left open, shorted, or terminated but undriven, ensuring reliable data communication even in the event of line faults.
The LTC1481IS8#PBF boasts an impressive driver output capability, able to drive up to 60 mA of output current, and supports data rates up to 2.5Mbps. This enables the device to handle long cable runs and the capacitive loads typical in industrial environments. Moreover, the transceiver features thermal shutdown protection, which prevents damage from excessive power dissipation.
Packaged in an 8-lead SOIC, the LTC1481IS8#PBF is characterized for operation from -40°C to 85°C, suitable for most industrial temperature ranges. Its small form factor and low power requirements make it an ideal choice for compact and efficient designs.
Key features of the LTC1481IS8#PBF include:
- Low Power Operation: 1.5mA Supply Current
- 4.75V to 5.25V Supply Voltage
