EIA-485/EIA-422 Quad Differential Receivers
General Description
Features
The DS96F173 and the DS96F175 are high speed quad differential line receivers designed to meet the EIA-485 standard. The DS96F173 and the DS96F175 offer improved
performance due to the use of L-FAST bipolar technology.
The use of LFAST technology allows the DS96F173 and
DS96F175 to operate at higher speeds while minimizing power consumption.
The DS96F173 and the DS96F175 have TRI-STATE® outputs and are optimized for balanced multipoint data bus transmission at rates up to 15 Mbps. The receivers feature high
input impedance, input hysteresis for increased noise immunity, and input sensitivity of 200 mV over a common mode
input voltage range of −7V to +12V. The receivers are therefore suitable for multipoint applications in noisy environments.
The DS96F173 features an active high and active low Enable,
common to all four receivers. The DS96F175 features separate active high Enables for each receiver pair.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
Note 2: Above TA = 25°C derate J package 10 mW/°C, W package 6.90 mW/°C, E package 11.11 mW/°C.
Note 3: ICC is tested with outputs disabled (worst case), ICC enabled is guaranteed by this test.
Note 4: VOH & VOL are tested over common mode voltage range of +/−12V via the VTH / VTL tests.
Note 5: Guaranteed by VOL & VOH tests.
Note 6: Guaranteed by IOZ test.
Note 7: Testing at 20pF assures conformance to spec at 5pF.
Note 8: Only one output at a time should be shorted.
