DESCRIPTION

L5170 is an octal line driver unit in DIP28 and
PLCC28 packages intended for use in the EIA std
RS232D, RS423A and CCITT V.10 and V.28 ap­plications.
With no external components L5170 is able to
drive a line up to 5000ft assuming the line capaci­tance is 35pFper ft and the capacitanceof the fil­ter connectors/protection components add up to

Note 1: The Output under load mustnot drop below 90% of the open circuitdrive level.
Note 2: This represents the static condition only. Applicationscan see 130mA normal current draw for clock and data lines with up to 500mA

transients when all linesaretransitioningat the sametime. Over 500ftof cable slew rate is governedby thedrivers ability to sink current.
The currents are rougly equivalentto the short circuit current.
