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.
The Auto Power-Off mode helps to save ...
