DATASHEET

5V, ±15kV ESD Protected, Two Port, Dual Protocol

(RS-232/RS-485) Transceivers

ISL33354E, ISL33357E

Features

The ISL33354E, ISL33357E are two port interface ICs where

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

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

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

• Operates from a single 5V supply

• Two independent ports: port 1 set for RS-232 (2 transceivers)

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

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

output levels from a single V supply as low as 4.5V. The

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

the same side) simplify board layouts

transceivers are RS-232 compliant, with the Rx inputs

handling up to ±25V.

• Pb-free (RoHS compliant)

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

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.

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

• User selectable RS-485 data rates

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

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

• Fast RS-232 data rate . . . . . . . . . . . . . . 460kbps (Minimum)

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

• Low current shutdown mode . . . . . . . . . . . . . . . . . . . . . . 55µA

• QFN package saves board space (ISL33357E only)

The ISL33354E and ISL33357E also include a shutdown

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

charge pumps and places the IC in a low current (55µA) mode.

Applications

• Gaming applications (e.g., slot machines)

The ISL33357E is a QFN packaged device for space

constrained applications.

• Single board computers
