Additional Details

The SP485EEN-L/R operates from a single 5V power supply. It features a driver enable (DE) and receiver enable (RE) control, allowing the transceiver to be easily configured for different operating modes. The driver outputs are protected against short circuits, and the receiver inputs are protected against ±15kV HBM electrostatic discharge. The device is available in an 8-pin SOIC package. The L/R suffix likely denotes different reel sizes or packaging options.
