L5170
OCTAL LINE DRIVER
ADVANCE DATA
OCTAL LINE DRIVER FOR:
EIA STD: RS232D; RS423A
CCIT: V.10; V.28
NO EXTERNAL COMPONENTS
VERY LONG TRANSMISSION LINE (5000ft)
50V EOS OUTPUT PROTECTION
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 ap-
plications.
With no external components L5170 is able to
drive a line up to 5000ft assuming the line capaci-
tance is 35pF per ft and the capacitance of the fil-
ter connectors/protection components add up to
the total capacitance load. The drivers typically
run in short circuit current mode whenever the ca-
ble attached is over 500ft.
This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice.

Note 1: The Output under load must not drop below 90% of the open circuit drive level.
Note 2: This represents the static condition only. Applications can see 130mA normal current draw for clock and data lines with up to 500mA
transients when all lines are transitioning at the same time. Over 500ft of cable slew rate is governed by the drivers ability to sink current.
The currents are rougly equivalent to the short circuit current.
