The ISL33334E, ISL33337E 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/RS-422 transceiver.
The on-board charge pump generates RS-232 compliant ±5V
Tx output levels from a single VCC supply as low as 3.15V. The
transceivers are RS-232 compliant, with the Rx inputs
handling up to ±25V.
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.
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.
