UC5171

UC5171 Octal Line Driver FEATURES Eight Single-Ended Line Drivers in One Package Digital Selection of High Mode EIA232E/CCITT V.28 only, and Low Mode EIA232E/V.28 & EIA423A/CCITT V.10/X.26 Single External Resistor Controls Slew Rate Wide Supply Voltage Range Tri-State Outputs Output Short-Circuit Protection Low Power Consumption 2kV ESD Protection on all Pins CONNECTION DIAGRAMS N PACKAGE (TOP VIEW) DESCRIPTION The UC5171 is a single-ended octal line driver designed to meet both standard modem control applications (EIA232E/V.28), and long line drive applications (EIA423A/V.10/X.26). The slew rate for all 8 drivers is controlled by a single external resistor. The slew rate and output levels in Low Mode are independent of the power variations. Mode selection is accomplished by the select pin Ms logic “low” for low output mode (EIA232E/V.28 & EIA423A/V.10) or pin Ms logic “high” for high mode (EIA232E/V.28). High mode should only be used to drive adapters that take power from the control lines, or applications using high threshold receivers.
