SP485R

1/10th Unit Load RS-485 Transceiver

FEATURES

• Allows Over 400 Transceivers On A

Transmission Line (ꢀ/ꢀ0th Unit Load)

• High Impedance on Receiver Inputs

(R_IN= 150kΩ typical)

• Half-Duplex Conﬁguration Consistent

With Industry Standard Pinout

• -7V to +ꢀ2V Common Mode Input

Voltage Range

• Low Power Consumption (250mW)

• Separate Driver and Receiver Enable

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.
