DS96F173C/DS96F173M/DS96F175C/DS96F175M
EIA-485/EIA-422 Quad Differential Receivers
General Description
The DS96F173 and the DS96F175 are high speed quad dif-
ferential line receivers designed to meet the EIA-485 stan-
dard. The DS96F173 and the DS96F175 offer improved per-
formance 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® out-
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 environ-
ments. 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.
