The TRSF3222E consists of two line drivers, two line  
receivers, and a dual charge-pump circuit with  
±15-kV ESD protection pin to pin (serial-port  
connection pins, including GND).

The TRSF3222E meets the requirements of  
TIA/EIA-232-F and provides the electrical interface  
between an asynchronous communication controller  
and the serial-port connector. The charge pump and  
four small external capacitors allow operation from a  
single 3-V to 5.5-V supply. The TRSF3222E  
operates at typical data signaling rates up to  
1000 kbit/s and is an improved drop-in replacement  
for industry-popular '3222 two-driver, two-receiver  
functions.

The TRSF3222E can be placed in the power-down mode by setting the power-down (PWRDOWN) input low,  
which draws only 1 μA from the power supply. When the device is powered down, the receivers remain active  
while the drivers are placed in the high-impedance state. Also, during power down, the onboard charge pump is  
disabled; V+ is lowered to VCC, and V– is raised toward GND. Receiver outputs also can be placed in the  
high-impedance state by setting enable (EN) high.
