DESCRIPTI ON

The UC5170C is a single-ended octal line driver designed to meet both
standard mod em control applicati ons (EIA232E/V.28), and long line drive
applications (EIA423A/V.10/X.26). The slew rate for all eight drivers is con­trolled by a single external resistor. The slew rate and o utput levels in Low
Mode are independent of the power variations.

Mode selection is easi ly accomplished by taking the select pins (M

S+ and

M

S-) 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.
