DATASHEET ISL83483, ISL83485, ISL83488, ISL83490, ISL83491 FN6052 Rev.5.00 3.3V, Low Power, High Speed or Slew Rate Limited, RS-485/RS-422 Transceivers Nov 21, 2018 These Renesas RS-485/RS-422 devices are BiCMOS 3.3V Features powered, single transceivers that meet both the RS-485 and Operate from a single +3.3V supply (10% tolerance) RS-422 standards for balanced communication. Unlike competitive devices, this Renesas family is specified for 10% Interoperable with 5V logic tolerance supplies (3V to 3.6V). High data rates up to 10Mbps The ISL83483 and ISL83488 use slew rate limited drivers Single unit load allows up to 32 devices on the bus which reduce EMI, and minimize reflections from improperly Slew rate limited versions for error free data transmission terminated transmission lines, or unterminated stubs in (ISL83483, ISL83488) .up to 250kbps multidrop and multipoint applications. Low current Shutdown mode (ISL83483, ISL83485, Data rates up to 10Mbps are achievable by using the ISL83491) 15nA ISL83485, ISL83490, or ISL83491, which feature higher slew rates. -7V to +12V common-mode input voltage range Three-state Rx and Tx outputs (except ISL83488, Logic inputs (for example, DI and DE) accept signals in ISL83490) excess of 5.5V, making them compatible with 5V logic families. 10ns propagation delay, 1ns skew (ISL83485, ISL83490, ISL83491) Receiver (Rx) inputs feature a fail-safe if open design, which ensures a logic high output if Rx inputs are floating. All Full duplex and half duplex pinouts devices present a single unit load to the RS-485 bus, which Current limiting and thermal shutdown for driver overload allows up to 32 transceivers on the network. protection Driver (Tx) outputs are short-circuit protected, even for Pb-free (RoHS compliant) voltages exceeding the power supply voltage. Additionally, on-chip thermal shutdown circuitry disables the Tx outputs to Applications prevent damage if power dissipation becomes excessive. Factory automation The ISL83488, ISL83490, and ISL83491 are configured for Security networks full duplex (separate Rx input and Tx output pins) applications. The ISL83488 and ISL83490 are offered in Building environmental control systems space saving 8 Ld packages for applications not requiring Rx Industrial/process control networks and Tx output disable functions (for example, point-to-point Level translators (for example, RS-232 to RS-422) and RS-422). Half duplex configurations (ISL83483, ISL83485) multiplex the Rx inputs and Tx outputs to provide RS-232 Extension Cords transceivers with Rx and Tx disable functions in 8 Ld packages.
