SP485RCN Datasheet

RS-485 Interface IC


The SP481R and SP485RCN are pin-to-pin equivalent with our existing SP485 product and contain enhancements such as higher ESD tolerance and 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. Each device is packaged in an 8-pin plastic DIP or 8-pin narrow SOIC package. The SP481Roffers a shutdown feature via the enable pins which will reduce the supply current (ICC) below 0.5&micro;A typical. SP485RCN Features &bull; Allows Over 400 Transceivers On A Transmission Line (1/10th Unit Load)&bull; High Impedance on Receiver Inputs (RIN = 150k&Omega; typical)&bull; Half-Duplex Configuration Consistent With Industry Standard Pinout&bull; &ndash;7V to +12V Common Mode Input Voltage Range&bull; Includes Shutdown Mode (ICC < 10&micro;A) (For SP481R Only)&bull; Low Power Consumption (250mW)&bull; Separate Driver and Receiver Enable
