DESCRIPTION/ORDERING INFORMATION  
The TRS3238 consists of five line drivers, three line receivers, and a dual charge-pump circuit with ±15-kV ESD  
(HBM) protection pin to pin (serial-port connection pins, including GND). The device meets the requirements of  
TIA/EIA-232-F and provides the electrical interface between notebook and subnotebook computer applications.  
The charge pump and four small external capacitors allow operation from a single 3-V to 5.5-V supply. In  
addition, the device includes an always-active noninverting output (ROUT1B), which allows applications using  
the ring indicator to transmit data while the device is powered down. The TRS3238 operates at data signaling  
rates up to 250 kbit/s and a maximum of 30-V/μs driver output slew rate.  
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 occurs if there  
is no activity in the logic levels for the driver inputs. 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. INVALID is low (invalid  
data) if all receiver input voltages are between –0.3 V and 0.3 V for more than 30 μs. Refer to 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.

TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard  
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where  
mandated by government requirements, testing of all parameters of each product is not necessarily 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 products or services or a  
warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual  
property of the third party, or a license from TI under the patents or other intellectual property of TI.  
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied
