DS9638QML
RS-422 Dual High Speed Differential Line Driver
General Description
Features
The DS9638 is a Schottky, TTL compatible, dual differential
line driver designed specifically to meet the EIA Standard
RS-422 specifications. It is designed to provide unipolar dif-
ferential drive to twisted pair or parallel wire transmission
lines. The inputs are TTL compatible. The outputs are similar
to totem pole TTL outputs, with active pull-up and pull-down.
The device features a short circuit protected active pull-up
with low output impedance and is specified to drive 50Ω trans-
mission lines at high speed. The mini-DIP provides high pack-
age density.
Single 5V supply

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
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
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.
