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.

The above data were taken by the ∆VEB method mounting on a glass epoxy board (40 × 40 × 1.6 mm) of 10% wiring density. 2. The absolute maximum ratings are values which must not individually be exceeded, and furthermore, no two of which may be realized at the same time.
