Maxim Integrated (MAX489EEPD+) Transceiver RS422, RS485

Product OverviewThe MAX489EEPD+ is a ±15KV ESD protected, slew rate limited, low powerRS485/RS422 transceiver in 14 pin DIP package. This device is used as a lowpower transceiver for RS485 and RS422 communications in harsh environments. Thedriver output and receiver input is protected against ±15KV electro staticdischarge (ESD) shocks without latch-up. The reduced slew rate driver minimizesEMI and reduces reflections caused by improperly terminated cables, thusallowing error free data transmission up to 250Kbps. The driver is short circuitcurrent limited and is protected against excessive power dissipation by thermalshutdown circuitry that places the driver outputs into a high impedance state.It features fail-safe circuitry which has a logic high receiver output when thereceiver input is open.Supply voltage range from 4.75V to 5.25VOperating temperature range from -40°C to 85°CDesigned for full duplex communicationFeatures receiver/driver enable functionQuiescent current is 120µAAllows up to 32 transceivers on the busApplicationsCommunications & Networking, IndustrialProduct InformationDevice Type: TransceiverIC Interface Type: RS422, RS485No. of Drivers: 1DriversNo. of Receivers: 1ReceiversSupply Voltage Min: 4.75VSupply Voltage Max: 5.25VDriver Case Style: DIPNo. of Pins: 14PinsOperating Temperature Min: -40°COperating Temperature Max: 85°CProduct Range: -Automotive Qualification Standard: -MSL: MSL 1 - UnlimitedIC Generic Number: MAX489E
