description  
The MC3487 offers four independent differential line drivers designed to meet the specifications of ANSI  
EIA/TIA-422-B and ITU Recommendation V.11. Each driver has a TTL-compatible input buffered to reduce  
current and minimize loading.  
The driver outputs utilize 3-state circuitry to provide high-impedance states at any pair of differential outputs  
when the appropriate output enable is at a low logic level. Internal circuitry is provided to ensure a  
high-impedance state at the differential outputs during power-up and power-down transition times provided the  
output enable is low. The outputs are capable of source or sink currents of 48 mA.  
The MC3487 is designed for optimum performance when used with the MC3486 quadruple line receiver. It is  
supplied in a 16-pin dual-in-line package and operates from a single 5-V supply.  
The MC3487 is characterized for operation from 0°C to 70°C.
