Product Summary
The SP485RCN is a 1/10th Unit Load RS-485 Transceiver. The SP485RCN is pin-to-pin equivalent with our existing SP485 product and contains 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. The SP485RCN is packaged in an 8-pin plastic DIP or 8-pin narrow SOIC package.
Parametrics
SP485RCN absolute maximum ratings: (1)VCC: +7V; (2)Storage Temperature: -65℃ to +150℃; (3)Power Dissipation: 1000mW; (4)Package Derating: 62 ℃/W.
Features
SP485RCN features: (1)Allows Over 400 Transceivers On A Transmission Line(1/10th Unit Load); (2)High Impedance on Receiver Inputs (RIN = 150kΩ typical); (3)Half-Duplex Configuration Consistent With Industry Standard Pinout; (4)–7V to +12V Common Mode Input Voltage Range; (5)Includes Shutdown Mode (ICC < 10μA) (For SP481R Only); (6)Low Power Consumption (250mW); (7)Separate Driver and Receiver Enable.
