description/ordering information  
The SN65C3221 and SN75C3221 consist of one line driver, one line receiver, and a dual charge-pump circuit  
with 15-kV ESD protection pin to pin (serial-port connection pins, including GND). These 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. These 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 devices do not sense a valid RS-232 signal on the receiver input, the driver output is disabled.  
If FORCEOFF is set low and EN 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. Refer to Figure 5 for receiver input levels.

(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.  
(2)  
Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), 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.  
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and  
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS  
compatible) as defined above.

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
