DESCRIPTION/ORDERING INFORMATION
The SN65C3221E and SN75C3221E consist 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). 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. See Figure 5 for receiver input levels.

(1) 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.
(2) All voltages are with respect to network GND.
(3) Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
(4) The package thermal impedance is calculated in accordance with JESD 51-7.

(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
temperature.
