DESCRIPTION/ORDERING INFORMATION
The SN75185 combines three drivers and five
receivers from the TI SN75188 and SN75189 bipolar
quadruple drivers and receivers, respectively. The
pinout matches the flow-through design of the
SN75C185 to decrease the part count, reduce the
board space required, and allow easy interconnection
of the UART and serial-port connector of IBM™
PC/AT™ and compatibles. The bipolar circuits and
processing of the SN75185 provide a rugged low-cost
solution for this function at the expense of quiescent
power and external passive components relative to
the SN75C185.
The SN75185 complies with the requirements of the
TIA/EIA-232-F and ITU v.28 standards. These
standards are for data interchange between a host
computer and peripheral at signaling rates up to 20
kbit/s. The switching speeds of the SN75185 are fast
enough to support rates up to 120 kbit/s with lower
capacitive loads (shorter cables). Interoperability at
the higher signaling rates cannot be assured unless
the designer has design control of the cable and the
interface circuits at both ends. For interoperability at
signaling rates to 120 kbit/s, use of TIA/EIA-423-B
(ITU v.10) and TIA/EIA-422-B (ITU v.11) standards is
recommended.

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.
All voltages are with respect to the network ground terminal.
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.
The package thermal impedance is calculated in accordance with JESD 51-7.
RS-232 pins are tested with respect to ground and to each other.
Per MIL-PRF-38535
RS-232 pins are tested with respect to ground.

The algebraic convention, in which the more positive (less negative) limit is designated as maximum, is used in this data sheet for logic
levels only (e.g., if –10 V is maximum, the typical value is a more negative voltage).
Output short-circuit conditions must maintain the total power dissipation below absolute maximum ratings.
Test conditions are those specified by TIA/EIA-232-F and as listed above.

APPLICATION INFORMATION
Diodes placed in series with the VDD and VSS leads protect the SN75185 in the fault condition. In the fault
condition, the device outputs are shorted to ±15 V, and the power supplies are at low and provide low-impedance
paths to ground (see Figure 15).

RS-232 maximum slew-rate requirement of 30 V/μs. The value of the loading capacitors required depends on the line
length and desired slew rate, but typically is 330 pF.

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), 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

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

business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.
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

provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in

the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.

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.
