UC5170C
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.
