Renesas ISL3179EFBZ

ТрансиверRS422, RS48540 Мбит/с

Overview

The ISL3179EFBZ is a high ESD protected 3.3V Powered Single Transceiver that meet both the RS-485 and RS-422 standards for balanced communication. Each device has low bus currents (+220µA/-150µA), 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 specification's 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 undriven. The ISL3180E is configured for full duplex applications. The ISL3179EFBZ 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.
