Renesas Electronics ISL3177EIBZ Line Transceiver, 8-Pin MSOP

The Renesas ISL317xE are ±15kV IEC61000 ESD protected, 3.3V powered single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. These devices have very low bus currents (+125μA/-100μA), so they present a true “1/8 unit load” to the RS-485 bus. This allows up to 256 transceivers on the network without violating the RS-485 specification’s 32 unit load maximum, and without using repeaters.

-7V to +12V common-mode input/output voltage range
It has half and full duplex pinouts
It has three state Rx and Tx outputs available
There is current limiting and thermal shutdown for driver overload protection
