May 1998

General Description

The DS96F173 and the DS96F175 are high speed quad dif­ferential line receivers designed to meet the EIA-485 stan­dard. The DS96F173andthe 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
puts 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 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 0˚C to +70˚C range for the DS96F173C/DS96F175C. All typicals are given for V
= 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: The algebraic convention, when the less positive (more negative) limit is designated minimum, is used in this data sheet for common mode input voltage

and threshold voltage levels only.

Note 6: Hysteresis is the difference between the positive-going input threshold voltage. V
Note 7: Refer to EIA-485 Standard for exact conditions.
Note 8: Only one output at a time should be shorted.
