DS26F31M

Quad High Speed Differential Line Drivers

General Description

The DS26F31 is a quad differential line driver designed for

digital data transmission over balanced lines. The DS26F31

meets all the requirements of EIA Standard RS-422 and

Federal Standard 1020. It is designed to provide unipolar dif-

ferential drive to twisted-pair or parallel-wire transmission

lines.

The DS26F31 offers improved performance due to the use

of state-of-the-art L-FAST bipolar technology. The L-FAST

technology allows for higher speeds and lower currents by

utilizing extremely short gate delay times. Thus, the

DS26F31 features lower power, extended temperature

range, and improved specifications.

The circuit provides an enable and disable function common

to all four drivers. The DS26F31M features TRI-STATE® out-

puts and logical OR-ed complementary enable inputs. The

inputs are all LS compatible and are all one unit load.

The DS26F31M offers optimum performance when used

with the DS26F32 Quad Differential Line Receiver.
