DESCRIPTION/ORDERING INFORMATION  
The TRSF3223 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 device 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 device 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 device does not sense a valid RS-232 signal, the driver outputs are disabled. If FORCEOFF is  
set low and enable (EN) is high, both drivers and receivers are shut off, and the supply current is reduced to  
1 μA. Disconnecting the serial port or turning off the peripheral drivers causes auto-powerdown 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 any receiver input. The INVALID output is  
used to notify the user if an RS-232 signal is present at any receiver input. INVALID is high (valid data) if any  
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. Refer to Figure 4 for receiver input levels.
