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 DIP28 PLCC28 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 35pF per ft and the capacitance of the filter connectors/protection components add up to BLOCK DIAGRAM ORDERING NUMBERS: L5170A L5170D the total capacitance load. The drivers typically run in short circuit current mode whenever the cable attached is over 500ft.

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. 3/9 L5170 AC ELECTRICAL CHARACTERISTICS (continued) Symbol tlz tnz tzl tzh tplh tph1 Propagation (see figure 4C) R L = 450Ω; CL = 50pF R slew = 2KΩ 0.3 0.3 Parameter Output Enable to Output (see figure 4B) Test Condition R L = 450Ω; CL = 50pF R slew = 10KΩ Min.
