SP485EP

The SP485EP is one member of the SP485 series and designed as one kind of 1/10th unit load RS-485 transceiver 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.

Features of the SP485EP are:(1)allows over 400 transceivers on a transmission line (1/10th unit load);(2)high impedance on receiver inputs (Rin=150k 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.

The absolute maximum ratings of the SP485EP can be summarized as:(1)Vcc:+7V;(2)storage temperature:-65°C to +150°C;(3)power dissipation:8-pin plastic DIP:1000mW;(4)8-pin plastic DIP:62 °C/W;(5)8-pin plastic N-SOIC:62 °C/W.If you want to know more information such as the electrical AC characteristics about the SP485EP,please download the datasheet in www.seekic.com .
