GM3088EMA

The GM3088E/GM13088E are 3.0~5.5V, +15kV ESD-protected, RS-485/RS-422 transceiver features one driver and one receiver. The device includes fail-safe circuitry, guaranteeing a logic-high receiver output when receiver inputs are open or shorted. The receiver outputs a logic-high if all transmitters on a terminated bus are disabled (high impedance). The GM13088E includes a hot-swap capability to eliminate false transitions on the bus during power-up or hot insertion. The GM3088E/GM13088E transmit at up to 16Mbps. The GM3088E/GM13088E is ideal for half-duplex communications and it draws 0.5mA of supply current when unloaded or when fully loaded with the drivers disabled. The GM3088E/GM13088E has a 1/8-unit load receiver input impedance, allowing up to 256 transceivers on the bus. The GM3088E/GM13088E is available in SOP8/MSOP8/DFN packages.
