Maxim Integrated (MAX491ECPD+) Transceiver RS422, RS485

Product OverviewThe MAX491ECPD+ is a ±15KV ESD protected, low power RS485/RS422 transceiver in14 pin DIP package. This device is used as a low power transceiver for RS485 andRS422 communications in harsh environments. The driver output and receiver inputis protected against ±15KV electro static discharge (ESD) shocks withoutlatch-up. The slew rate is not limited allowing it to transmit up to 2.5Mbps.The driver is short circuit current limited and is protected against excessivepower dissipation by thermal shutdown circuitry that places the driver outputsinto a high impedance state. It features fail-safe circuitry which has a logichigh receiver output when the receiver input is open.Supply voltage range from 4.75V to 5.25VOperating temperature range from 0°C to 70°CDesigned for full duplex communicationFeatures receiver/driver enable functionQuiescent current is 300µAAllows up to 32 transceivers on the busApplicationsCommunications & Networking, Industrial
