D or N PACKAGE
The SN65LBC175A and SN75LBC175A are
quadruple differential line receivers with 3-state
outputs, designed for TIA/EIA-485 (RS-485),
TIA/EIA-422 (RS-422), and ISO 8482 (Euro
These devices are 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
Each 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 LinBiCMOSt, facilitating low power consumption and
Two EN inputs provide pair-wise enable control, or these can be tied together externally to enable all four drivers
with the same signal.
The SN75LBC175A is characterized for operation over the temperature range of 0°C to 70°C. The
SN65LBC175A is characterized over the temperature range from −40°C to 85°C.
