N PACKAGE (TOP VIEW) Q PACKAGE (TOP VIEW) Octal Line Driver FEATURES • Eight Single Ended Line Drivers in One Package • Meets EIA Standards EIA232E/V.28, EIA423A and CCITT V.10/X.26 • Single External Resistor Controls Slew Rate • Wide Supply Voltage Range • Tri-State Outputs • Output Short-Circuit Protection DESCRIPTION The UC5170C 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 eight drivers is con- trolled by a single external resistor. The slew rate and output levels in Low Mode are independent of the power variations. Mode selection is easily accomplished by taking the select pins (MS+ and MS-) to ground for low output mode (EIA232E/V.28 and EIA423A/V.10) or to their respective supplies for high mode (EIA232E/V.28). High mode should only by used to drive adapters that take power from the control lines, or applications using high threshold receivers.
