Renesas Electronics America Inc. ISL83072E series Drivers Interface ICs

The ISL83072E series of drivers interface ICs are ±15kV ESD Protected, 3.3V, full fail-safe, low power, high speed or slew rate limited, RS-485/RS-422 transceivers. They are BiCMOS 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 (+125mA/-100mA), so they present a true “1/8 unit load” to the RS-485 bus. The ISL83070E through ISL83075E utilize slew rate limited drivers which reduce EMI, and minimize reflections from improperly terminated transmission lines, or unterminated stubs in multidrop and multipoint applications1. Slew rate limited versions also include receiver input filtering to enhance noise immunity in the presence of slow input signals. The ISL83070E, ISL83071E, ISL83073E, ISL83076E, ISL83077E are configured for full duplex (separate Rx input and Tx output pins) applications. The half duplex versions multiplex the Rx inputs and Tx outputs to allow transceivers with output disable functions in 8 lead packages.
