description

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

RS-485) applications.

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

environment.

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 LinBiCMOS

t, facilitating low power consumption and

inherent 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.

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.
