(1) The signaling rate of a line is the number of voltage
transitions that are made per second expressed in the units
bps (bits per second).
3 Description
The SN65LBC175A-EP is a quadruple differential line
receiver with 3-state outputs, designed for TIA/EIA-
485 (RS-485), TIA/EIA-422 (RS-422), and ISO 8482
(Euro RS-485) applications.
This device is optimized for balanced multipoint bus
communication at data rates up to and exceeding 50
million bits per second. The transmission media may
be twisted-pair cables, printed-circuit board traces, or
backplanes. The ultimate rate and distance of data
transfer is dependent upon the attenuation
characteristics of the media and the noise coupling to
the environment.
The receiver operates over a wide range of positive
and negative common-mode input voltages, and
features ESD protection to 6 kV, making it suitable for
high-speed multipoint data transmission applications
in harsh environments. These devices are designed
using LinBiCMOS^®, facilitating low power
consumption and robustness.
Two EN inputs provide pair-wise enable control, or
these can be tied together externally to enable all four
drivers with the same signal.
