HD293487
Quadruple Differential Line Drivers With 3 State Outputs
ADE-205-585 (Z)
1st. Edition
Dec. 2000
Description
The HD293487 features line drivers which satisfy the requirements of EIA RS-422 A. This device is
designde to provide differential signals with high current capability on bus lines. When the enable input is
low, the associated outputs are in a high impedance state. The output circuit has active pull up and pull
down and is capable of sinking and sourcing 48 mA.
