Maxim Integrated (MAX491CPD+) Transceiver RS422, RS485

Product Overview The MAX491CPD+ is a low power RS485/RS422 transceiver in 14 pin DIP package. It contains one driver and one receiver. 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 excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high impedance state. It features fail-safe circuitry which has a logic high receiver output when the receiver input is open. Supply voltage range from 4.75V to 5.25V Operating temperature range from 0°C to 70°C Designed for full duplex communication Features receiver/driver enable function Quiescent current is 300µA Allows up to 32 transceivers on the bus Applications Communications & Networking, Industrial Product Information Device Type: Transceiver IC Interface Type: RS422, RS485 No. of Drivers: 1Drivers No. of Receivers: 1Receivers Supply Voltage Min: 4.75V Supply Voltage Max: 5.25V Driver Case Style: DIP No. of Pins: 14Pins Operating Temperature Min: 0°C Operating Temperature Max: 70°C Product Range: - Automotive Qualification Standard: - MSL: MSL 1 - Unlimited What's in the box 1 x Maxim Integrated (MAX491CPD+) Transceiver RS422
