description/ordering information  
The SN65C3223 and SN75C3223 consist 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 devices 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 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 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.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and  
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not  
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.  
NOTES: 1. All voltages are with respect to network GND.

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in  
a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.

Eco Plan  
-
The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS  
&
no Sb/Br)  
-
please check  
http://www.ti.com/productcontent for the latest availability information and additional product content details.  
TBD: The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements  
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered  
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame  
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)  
(3)  
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder  
temperature.
