The DS96F172 and the DS96F174 are high speed quad differential line drivers designed to meet EIA-485 Standards. The DS96F172 and the DS96F174 offer improved performance due to the use of L-FAST bipolar technology. The use of LFAST technology allows the DS96F172 and DS96F174 to operate at higher speeds while minimizing power consumption. The DS96F172 and the DS96F174 have TRI-STATE ® outputs and are optimized for balanced multipoint data bus transmission at rates to 15 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. The DS96F172 features an active high and active low Enable, common to all four drivers. The DS96F174 features separate active high Enables for each driver pair.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 DS96F174C. 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 reference 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 In EIA-422A and EIA-485 standards, 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. Note 8: For more information see Application Bulletin, contact Product Marketing.
