DESCRIPTION/ORDERING INFORMATION
The TRS3318E is a dual-driver, dual-receiver, RS-232-compatible transceiver. The device features
auto-powerdown plus and enhanced electrostatic discharge (ESD) protection integrated into the chip. Driver
output and receiver input are protected to ±15 kV using the IEC 61000-4-2 Air-Gap Discharge method, ±8 kV
using the IEC 61000-4-2 Contact Discharge method, and ±15 kV using the Human-Body Model (HBM).
The device operates at a data rate of 460 kbps. The transceiver has a proprietary low-dropout driver output
stage, enabling RS-232-compatible operation from a 2.25-V to 3-V supply with a dual charge pump. The charge
pump requires only four 0.1-µF capacitors and features a logic-level output (READY) that asserts when the
charge pump is regulating and the device is ready to begin transmitting.
The TRS3318E achieves a 1-µA supply current using the auto-powerdown feature. This device automatically
enters a low-power power-down mode when the RS-232 cable is disconnected or the drivers of the connected
peripherals are inactive for more than 30 s. The device turns on again when it senses a valid transition at any
driver or receiver input. Auto-powerdown saves power without changes to the existing BIOS or operating
system.
This device is available in two space-saving packages: 20-pin SSOP and 20-pin TSSOP.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of the Texas
Instruments standard warranty. Production processing does not
necessarily include testing of all parameters.

DETAILED DESCRIPTION
Flexible control options for power management are featured when the serial port and driver inputs are inactive.
The auto-powerdown plus feature functions when FORCEON is low and FORCEOFF is high. During this mode
of operation, if the device does not sense valid signal transitions on all receiver and driver inputs for
approximately 30 s, the built-in charge pump and drivers are powered down, reducing the supply current to
1 µA. By disconnecting the serial port or placing the peripheral drivers off, auto-powerdown plus can be disabled
when FORCEON and FORCEOFF are high. With auto-powerdown plus enabled, the device activates
automatically when a valid signal is applied to any receiver or driver 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 (typical number). INVALID is low (invalid data) if all receiver input voltage are between –0.3 V and
0.3 V for more than 30 µs (typical number).

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.
V+ and V– can have maximum magnitudes of 7 V, but their absolute difference cannot exceed 13 V.

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)

performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should
provide adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask
work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services
are used. Information published by TI regarding third-party products or services does not constitute a license from TI to use such

Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service
voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business
practice. TI is not responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would
reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement
specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications
of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related
requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any
applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its
representatives against any damages arising out of the use of TI products in such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are

specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is
solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in
connection with such use.

are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any
non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
