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.

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.
