L5170A Overview
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 ponents 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 ponents add up to BLOCK DIAGRAM ORDERING NUMBERS: L5170A L5170D the total capacitance load.
