Integrated circuit K5559IN10ASI

The RS-485/422 transceiver IC for organising a half-duplex communication channel according to the corresponding standards.The transmitter outputs have a limitation of the rate of rise/drop of the output signal to reduce the level of electromagnetic interference, as well as reflections at non-ideally matched bus.The input impedance of the receiver corresponds to 1/8 unit of load (1/8 U.L.), which allows parallel inclusion of up to 256 equivalent transceivers on the bus.Fault-tolerant to the presence of short circuits and open circuits on the bus receiver circuit, which does not require the use of external fail-safe resistors.Hot-swap mode (hot-swap), eliminating the erroneous inclusion of the output of the transmitter and receiver at power supply.Supply voltage from 4.5 V to 5.5 V.Current consumption without load no more than 1.8 mA.Operating temperature range:minus 45 - 85 ° C.Type of housing: 8-pin plastic housing SO-8.
