UC5172  
Octal Line Driver  
FEATURES  
DESCRIPTION  
Eight Single-Ended Line Drivers in One  
Package  
The UC5172 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 are independent of the power variations.  
Meets Standards EIA232E/CCITT V.28,  
and EIA423A/CCITT V.10/X.26  
Single External Resistor Controls Slew  
Rate  
The UC5172 has high output current, and current balance for long line  
drive applications. EOS - Output parasitic SCRs powered on and off  
are 35V, well above signal levels, allowing protection devices to work.  
Wide Supply Voltage Range  
Tri-State Outputs  
Inputs are compatible TTL+MOS logic families and are diode protected  
against negative transients.  
Output Short-Circuit Protection  
Low Power Consumption  
2kV ESD Protection on all Pins
