SP485R
1/10th Unit Load RS-485 Transceiver
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.
