The ISL8488E, ISL8489E, ISL8490E, ISL8491E devices are ESD protected, BiCMOS, 5V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. Each driver output and receiver input is protected against ±15kV ESD strikes, without latch-up. Unlike competitive versions, these Intersil devices are specified for 10% tolerance supplies (4.5V to 5.5V).brbr These devices are configured for full duplex (separate Rx input and Tx output pins) applications, so they are ideal for RS-422 networks requiring high ESD tolerance on the bus pins. The ISL8488E, ISL8490E are 8 Ld versions without Rx and Tx output enables. The other two versions include Rx and Tx output enable pins in a standard 14 Ld pinout.brbr The ISL8488E, ISL8489E utilize slew rate limited drivers which reduce EMI, and minimize reflections from improperly terminated transmission lines, or unterminated stubs in multidrop and multipoint applications.brbr Data rates up to 10Mbps are achievable by using the ISL8490E, ISL8491E, which feature higher slew rates.brbr The devices present a "single unit load" to the RS-485 bus, which allows a total of 32 transmitters and receivers on the network. For "1/8 unit load" versions (256 devices on the bus), please refer to the ISL4489E, ISL4491E data sheet.brbr Receiver (Rx) inputs feature a "fail-safe if open" design, which ensures a logic high Rx output if Rx inputs are floating.brbr Driver (Tx) outputs are short circuit protected, even for voltages exceeding the power supply voltage. Additionally, on-chip thermal shutdown circuitry disables the Tx outputs to prevent damage if power dissipation becomes excessive.
