ETC HD75153

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.

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.

Notes: 1. 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. Differential and common mode output voltages.
