DESCRIPTION  
The ST3243 device consists of 3 drivers, 5  
receivers and a dual charge-pump circuit. The  
device meets the requirements of EIA/TIA and  
V.28/V.24 comunication standards providing high  
data rate capability.  
SSOP  
TSSOP  
The receiver R2 is always active to implement a  
wake-up feature for serial port.  
The ST3243 has a proprietary low-dropout  
transmitter output stage enabling true RS-232  
performance from a 3.0V to 5.5V supply with a  
dual charge pump. The device is guaranteed to  
run at data rates of 250kbps while maintaining  
RS-232 output levels.  
The Auto-powerdown feature functions when  
FORCEON is low and FORCEOFF is high. During  
this mode of operation, if the device does not  
sense a valid RS-232 signal, the driver outputs are  
disabled. If FORCEOFF is set low, both drivers  
and receivers (expert R2B) are shut off, and  
supply current is reduced to 1mA. Disconnecting  
the serial port or turning off the peripheral drives  
causes the auto-powerdown condition to occur.  
Auto-powerdown can be disabled when  
FORCEON and FORCEOFF are high, and should  
be done when driving a serial mouse. With  
Auto-powerdown enabled, the device is activated  
automatically when a valid signal is applied to any  
receiver input.  
Typical application are in notebook, subnotebook,  
palmtop computers, battery-powered equipment,  
hand-held equipment, peripherals and printers.
