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.
