ISO3086TDWR

5V隔离RS-485收发器，集成变压器驱动器 Isolated 5V RS-485 Transceiver With Integrated Transformer Driver

**Description**

The ISO3086T is an isolated differential line transceiver with integrated oscillator outputs that provide the primary voltage for an isolation transformer. The device is a full-duplex differential line transceiver for RS-485 and RS-422 applications that can easily be configured for half-duplex operation by connecting pin 11 to pin 14, and pin 12 to pin 13.
