Maxim Integrated (MAX491CPD+) Transceiver RS422, RS485

Product OverviewThe MAX491CPD+ is a low power RS485/RS422 transceiver in 14 pin DIP package. Itcontains one driver and one receiver. The slew rate is not limited allowing itto transmit up to 2.5Mbps. The driver is short circuit current limited and isprotected against excessive power dissipation by thermal shutdown circuitry thatplaces the driver outputs into a high impedance state. It features fail-safecircuitry which has a logic high receiver output when the receiver input isopen.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, 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: 0°COperating Temperature Max: 70°CProduct Range: -Automotive Qualification Standard: -MSL: MSL 1 - Unlimited
