ISL83483, ISL83485, ISL83488, ISL83490, ISL83491

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

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

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

RS-422 standards for balanced communication. Unlike

competitive devices, this Renesas family is specified for 10%

tolerance supplies (3V to 3.6V).

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.

Data rates up to 10Mbps are achievable by using the

ISL83485, ISL83490,

ISL83491,

which feature higher

slew rates.

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

excess of 5.5V, making them compatible with 5V logic

families.

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.

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.

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.
