(TOP VIEW)  
These four differential line drivers are designed  
for data transmission over twisted-pair or  
parallel-wire transmission lines. They meet the  
requirements of ANSI Standard EIA/TIA-422-B  
and ITU Recommendation V.11 and are  
compatible with 3-state TTL circuits. Advanced  
low-power Schottky technology provides high  
speed without the usual power penalty. Standby  
supply current is typically only 26 mA. Typical  
propagation delay time is less than 10 ns, and  
enable/disable times are typically less than  
16 ns.

High-impedance inputs keep input currents low:  
less than 1 µA for a high level and less than  
100 µA for a low level. The driver circuits can be  
enabled in pairs by separate active-high enable  
inputs. The SN55ALS194 and SN75ALS194 are  
capable of data rates in excess of 20 megabits  
per second and are designed to operate with the  
SN55ALS195 and SN75ALS195 quadruple line  
receivers.  
NC – No internal connection  
The SN55ALS194 is characterized for operation over the full military temperature range of 55°C to 125°C. The  
SN75ALS194 is characterized for operation from 0°C to 70°C.
