Renesas ISL3179EIBZ-T

ТрансиверRS422, RS48540 Мбит/с

Overview

The ISL3179EIBZ is an ESD protected Single Transceiver meets both the RS-485 and RS-422 standards for balanced communication. The device has low bus currents, so it presents a 1/5 unit load to the RS-485 bus. This allows up to 160 transceivers on the network without violating the RS-485 specifications 32 unit load maximum and without using repeaters. Receiver (Rx) inputs feature a full fail-safe design, which ensures a logic high Rx output if Rx inputs are floating, shorted or terminated but un-driven. The ISL3179EIBZ half duplex version multiplexes the Rx inputs and Tx outputs to allow a transceiver with an output disable function. Hot plug circuitry ensures that the Tx and Rx outputs remain in a high impedance state while the power supply stabilizes.
