DESCRIPTION  
SSOP  
TSSOP  
The ST3243E 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 communication standards providing  
high data rate capability and enhanced  
electrostatic discharge (ESD) protection. All  
transmitter outputs and receiver input are  
protected to ±8KV USING IEC 1000-4-2 contact  
discharge and ±15KV using the Human Body  
Model. The receiver R2 is always active to  
implement a wake-up feature for serial port.  
The ST3243E 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.  
disabled. If FORCEOFF is set low, both drivers  
and receivers (expert R2B) are shut off, and  
supply current is reduced to 1µA. 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.  
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  
Typical application are in notebook, subnotebook,  
palmtop computers, battery-powered equipment,  
hand-held equipment, peripherals and printers.
