General Description

The UM3243 series are 3-driver/5-receiver 3V-5.5V powered RS-232 transceivers featuring Auto Power-Off and low supply current, when no valid RS-232 level signal is sensed on any receiver inputs, the charge pump circuit and drivers will be powered off.

Disconnection of the RS-232 cable or poweroff of the transmitters of the attaching peripherals will lead to Power-Off mode.

When a valid level is applied to any RS-232 receiver inputs, the chip will turn on again.

Overview

UM3243 Low Supply Current, 3V to 5.5V, 250kbps, 3-Driver/5-Receiver, Enhanced ESD Protection Smart RS-232 Transceivers UM3243EEAS/UM3243EEASR/.

Key Features

enhanced ESD protection with ±15kV for human body mode and ±8kV for IEC61000-4-2 contact discharge mode.
