The DS96172 and DS96174 are high speed quad differential line drivers designed to meet EIA Standard RS-485. The devices have TRI-STATE ® outputs and are optimized for balanced multipoint data bus transmission at rates to 10 Mbps. The drivers have wide positive and negative common mode range for multipoint applications in noisy environments. Positive and negative current-limiting is provided which protects the drivers from line fault conditions over to -7.0V common mode range. A thermal shutdown feature is also provided and occurs at junction temperature of approximately 160°C. The DS96172 features an active high and active low Enable, common to all four drivers. The DS96174 features separate active high Enables for each driver pair. Compatible RS-485 receivers, transceivers, and repeaters are also offered to provide optimum bus performance. The respective device types are DS96175, DS96176 AND DS96177.Features

Note 2: "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices should be operated at these limits. The tables of "Electrical Characteristics" provide conditions for actual device operation. Note 3: Unless otherwise specified min/max limits apply across the to +70°C range for the DS96172/DS96174. All typicals are given for VCC = 5V and = 25°C. Note 4: All currents into the device pins are positive; all currents out of the device pins are negative. All voltages are referenced to ground unless otherwise specified. Note 5: |VOD| and |VOC| are the changes in magnitude of VOD and VOC respectively, that occur when the input is changed from a high level to a low level. Note 6: In EIA Standards RS-422A and RS-485, VOC, which is the average of the two output voltages with respect to ground, is called output offset voltage, VOS. Note 7: Only one output at a time should be shorted.FIGURE 1. Differential and Common Mode Output Voltage
