DESCRIPTION

The DS26F31M is a quad differential line driver

designed for digital data transmission over balanced

lines. The DS26F31M meets all the requirements of

EIA Standard RS-422 and Federal Standard 1020. It

is designed to provide unipolar differential drive to

twisted-pair or parallel-wire transmission lines.

The DS26F31M 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 DS26F31M 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 outputs 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.
