ISO7761DWR

The ISO7761DWR is a high-performance, single-channel, isolated RS-485 transceiver offered by Texas Instruments. It is designed to provide reliable communication in industrial and automotive applications where data integrity and noise immunity are crucial.

Description:

The ISO7761DWR is a monolithic device that combines an RS-485 transmitter and receiver with an integrated isolation barrier. The isolation barrier provides electrical isolation between the RS-485 interface and the system ground, which helps protect against ground loops, noise, and voltage transients. The device operates with a single 3.3V supply and offers a wide operating temperature range of -40°C to +105°C.

1. Single-channel, isolated RS-485 transceiver
2. Integrated isolation barrier for enhanced noise immunity
3. 3.3V single-supply operation
4. Wide operating temperature range: -40°C to +105°C
5. Low power consumption: 7.5mA (typical) in normal operation
6. Robust design for industrial and automotive applications
7. Supports data rates up to 10 Mbps
8. Short-circuit protection on both A and B lines
9. ±15kV ESD protection on all pins
10. Small package size: 6mm x 6mm WSON
