TIISO3088DWR
Overview
The ISO3088DWR is an isolated half-duplex RS-485 transceiver capable of data rates up to 20 Mbps. It provides 2500 VRMS galvanic isolation per UL 1577 and combines a silicon dioxide isolation barrier with a differential line transceiver to prevent ground loops in noisy environments.
Why Choose This Part
This device features high transient immunity of 50 kV/us and a fail-safe receiver that ensures a logic-high output if the bus is open, shorted, or idle. Its 20 Mbps signaling rate makes it suitable for high-speed protocols while maintaining low bus capacitance of 16 pF to support up to 256 nodes on a single bus.
Applications
Key Specifications
Getting Started
To evaluate this transceiver, designers can use the ISO308x evaluation modules from Texas Instruments. Ensure that VCC1 and VCC2 are properly decoupled with 0.1 uF capacitors and that the isolation barrier is respected in the PCB layout to maintain the 2500 VRMS rating.
