DATASHEET

ISL83483, ISL83485, ISL83488, ISL83490, ISL83491

3.3V, Low Power, High Speed or Slew Rate Limited, RS-485/RS-422 Transceivers

FN6052

Rev.5.01

Mar 12, 2020

These Renesas RS-485/RS-422 devices are BiCMOS 3.3V

powered, single transceivers that meet both the RS-485 and

Features

• Operate from a single +3.3V supply (10% tolerance)

• Interoperable with 5V logic

RS-422 standards for balanced communication. Unlike

competitive devices, this Renesas family is specified for 10%

tolerance supplies (3V to 3.6V).

• High data rates. . . . . . . . . . . . . . . . . . . . . . up to 10Mbps

• Single unit load allows up to 32 devices on the bus

The ISL83483 and ISL83488 use slew rate limited drivers

which reduce EMI, and minimize reflections from improperly

terminated transmission lines, or unterminated stubs in

multidrop and multipoint applications.

• Slew rate limited versions for error free data transmission

(ISL83483, ISL83488) . . . . . . . . . . . . . . . . .up to 250kbps

• Low current Shutdown mode (ISL83483, ISL83485,

ISL83491). . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .15nA

Data rates up to 10Mbps are achievable by using the

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,

ISL83490)

Logic inputs (for example, DI and DE) accept signals in

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

devices present a “single unit load” to the RS-485 bus, which

allows up to 32 transceivers on the network.

• Full duplex and half duplex pinouts

• Current limiting and thermal shutdown for driver overload

protection

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.

• Pb-free (RoHS compliant)

Applications

• Factory automation

The ISL83488, ISL83490, and ISL83491 are configured for

full duplex (separate Rx input and Tx output pins)

applications. The ISL83488 and ISL83490 are offered in

space saving 8 Ld packages for applications not requiring Rx

and Tx output disable functions (for example, point-to-point

and RS-422). Half duplex configurations (ISL83483,

ISL83485) multiplex the Rx inputs and Tx outputs to provide

transceivers with Rx and Tx disable functions in 8 Ld

packages.

• Security networks

• Building environmental control systems

• Industrial/process control networks

• Level translators (for example, RS-232 to RS-422)

• RS-232 “Extension Cords”
