General Description

The SP485R is a pin-to-pin equivalent to our existing SP485 product and offers a high receiver input impedance.

The higher receiver input impedance allows for connecting over 400 transceivers on a single transmission line without degrading the RS-485 driver signal.

The device is packaged in a 8-pin plastic DIP or 8-pin narrow SOIC.
