DESCRIPTION/ORDERING INFORMATION  
The TRSF3221 consists of one line driver, one line receiver, and a dual charge-pump circuit with ±15-kV IEC  
ESD protection pin-to-pin (serial-port connection pins, including GND). The TRSF3221 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 TRSF3221 operates at  
data signaling rates up to 1 Mbit/s and a driver output slew rate of 24 V/μs to 150 V/μs.  
Flexible control options for power management are available when the serial port is inactive. The  
auto-powerdown feature functions when FORCEON is low and FORCEOFF is high. During this mode of  
operation, if the TRSF3221 does not sense a valid RS-232 signal on the receiver input, the driver output is  
disabled. If FORCEOFF is set low and the enable (EN) input is high, both the driver and receiver are shut off,  
and the supply current is reduced to 1 μA. Disconnecting the serial port or turning off the peripheral drivers  
causes the auto-powerdown condition to occur. Auto-powerdown can be disabled when FORCEON and  
FORCEOFF are high. With auto-powerdown enabled, the device is activated automatically when a valid signal is  
applied to the receiver input. The INVALID output notifies the user if an RS-232 signal is present at the receiver  
input. INVALID is high (valid data) if the receiver input voltage is greater than 2.7 V or less than –2.7 V, or has  
been between –0.3 V and 0.3 V for less than 30 μs. INVALID is low (invalid data) if the receiver input voltage is  
between –0.3 V and 0.3 V for more than 30 μs. See Figure 5 for receiver input levels.
