DS26C32AMQML
Quad Differential Line Receiver
General Description
with 6 mA source and sink capability. This product is pin com-
patible with the DS26LS32A and the AM26LS32.
The DS26C32A is a quad differential line receiver designed
to meet the RS-422, RS-423, and Federal Standards 1020
and 1030 for balanced and unbalanced digital data transmis-
Features
■
CMOS design for low power
sion, while retaining the low power characteristics of CMOS.
±0.2V sensitivity over input common mode voltage range
Input fail-safe circuitry.
■
■
■
■
■
The DS26C32A has an input sensitivity of 200 mV over the
common mode input voltage range of ±7V. The DS26C32A
features internal pull-up and pull-down resistors which pre-
vent output oscillation on unused channels.
Inputs won't load line when VCC = 0V
Meets the requirements of EIA standard RS-422
TRI-STATE outputs for connection to system buses
The DS26C32A provides an enable and disable function com-
mon to all four receivers, and features TRI-STATE ® outputs

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
Note 2: Unless otherwise specified, all voltages are referenced to ground.

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,

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

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
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
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.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are
