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 lev-
els 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.
