3.3V, ±15kV ESD Protected, Two Port, Dual Protocol (RS-232/RS-485)

Transceivers

FN8776

Rev 1.00

October 21, 2016

The ISL33334E, ISL33337E are two port interface ICs where

Features

port 1 is configured as a dual (2 Tx, 2 Rx) RS-232 transceiver

and port 2 is a single RS-485/RS-422 transceiver.

• ±15kV (HBM) ESD protected bus pins (RS-232 or RS-485)

• Operates from a single 3.3V supply

The on-board charge pump generates RS-232 compliant ±5V

Tx output levels from a single V supply as low as 3.15V. The

transceivers are RS-232 compliant, with the Rx inputs

handling up to ±25V.

• Two independent ports, port 1 set for RS-232 (2 Transceivers)

and port 2 for RS-485/RS-422 (1 transceiver)

• True flow-through pinouts (Rx inputs and Tx outputs all on

the same side) simplify board layouts

The port 2 transceiver supports both the RS-485 and RS-422

differential communication standards. The receiver features

“full fail-safe” operation, so the Rx output remains in a high

state if the inputs are open or shorted together. The

• Pb-free (RoHS compliant)

• Full fail-safe (open/short) RS-485/422 Port 2 Rx

• User selectable RS-485 data rates

transmitter supports two data rates, one of which is slew rate

limited for problem free communication at low data rates. The

active low Rx enable pin (RE485) allows Tx/Rx direction

control, via a single signal, simply by connecting the

corresponding DE485 and RE485 pins together.

- Fast speed. . . . . . . . . . . . . . . . . . . . . . . . . . . . up to 20Mbps

- Slew rate limited . . . . . . . . . . . . . . . . . . . . . . up to 115kbps

• Fast RS-232 data rate . . . . . . . . . . . . . . . . . . . . up to 400kbps

• Small charge pump capacitors . . . . . . . . . . . . . . . . 4 x 0.1µF

• Low current shutdown mode . . . . . . . . . . . . . . . . . . . . . . 40µA

• QFN package saves board space (ISL33337E only)

The ISL33334E and ISL33337E also include a shutdown

function, which disables the Tx and Rx outputs, disables the

charge pumps and places the IC in a low current (40µA) mode.

The ISL33337E is a QFN packaged device for space

constrained applications.
