DS26F31M
Quad High Speed Differential Line Drivers
The DS26F31M offers optimum performance when used
with the DS26F32 Quad Differential Line Receiver.
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.
Features
n Military temperature range
n Output skew — 2.0 ns typical
n Input to output delay — 10 ns
n Operation from single +5.0V supply
n 16-lead ceramic DIP Package
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.
=
n Outputs won’t load line when VCC 0V
n Output short circuit protection
n Meets the requirements of EIA standard RS-422
n High output drive capability for 100Ω terminated
transmission lines
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.
