The SN65C3222E and SN75C3222E consist of two  
line drivers, two line receivers, and  
charge-pump circuit with ±15-kV ESD protection pin  
to pin (serial-port connection pins, including GND).

The devices meet the requirements of TIA/EIA-232-F  
and provide 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 devices operate at  
typical data signaling rates up to 1000 kbit/s and are  
improved drop-in replacements for industry-popular  
'3222 two-driver, two-receiver functions.

The SN65C3222E and SN75C3222E 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 devices are 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.
