YD3082E
Every spec below is cited to the manufacturer datasheet. Pick your exact ordering code, compare the closest alternatives, then ask the assistant what it means for your design.
What the YD3082E family does
The YD3082E is a fail-safe RS-485/RS-422 transceiver featuring a driver and receiver in a single SOP8 package. It operates on a 3.0V to 5.5V supply, supports data rates up to 1Mbps, and offers ±15kV Human Body Model ESD protection. The device draws 140μA in normal operation and 0.1μA in shutdown mode. Its fail-safe circuitry guarantees a logic-high receiver output when bus inputs are open or shorted. Engineers typically use this component for RS-485 communications, level translation, motor control, and industrial control local area networks.
