ADVANCE DATA
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.
