ILX3221

TECHNICAL DATA
Interface Transceiver of the Serial Data of
RS-232 Standard
ILX3221
DESCRIPTION
The ILX3221 is interface transceiver of serial data
under RS - 232 standard with single power supply
source & bipolar output voltage of transmitter, low power
consumption.
The ILX3221 is purposed for application in
modern high efficient calculating systems with the wide
range of supply voltage, fast-operating electronic
devices with high level of fidelity of information exchange
among distant devices. The chip is designed in 16-pin
SSOP and TSSOP package.
