HD75153 Quadruple Differential Line Drivers With 3 State Outputs HD75153 features line drivers which satisfy the requirements of EIA RS 422 A and Federal Standard 1020. This device is designed to provide differential signals with high current capability on bus lines. The circuit provides strobe and enable inputs to control all four drivers. The output circuit has active pull up and pull down and is capable of sinking or sourcing 40 mA.

The above date were taken by the ∆VBE 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.

All typical values are at V CC = 5 V, Ta = 25°C. ∆VOD and ∆VOC are the changes in magnitudes of V OD and VOC , respectively, that occur when the input is changed from a high level to a low level. 2. In EIA standard RS–422A, V OC, which is the average of the two output voltages with respect to ground, is called output offset voltage, V OS. 3. Only one output should be shorted at a time, and duration of the short circuit should not exceed one second. 4.
