These devices are optimized for balanced multipoint bus transmission at signalling rates up to 30 million bits per second. The transmission media may be printed-circuit board traces, backplanes, or cables. The ultimate rate and distance of data transfer is dependent upon the attenuation characteristics of the media and the noise coupling to the environment.

These devices are designed using LinBiCMOSt, facilitating low power consumption and robustness. The two EN inputs provide pair-wise driver enabling, or can be externally tied together to provide enable control of all four drivers with one signal. When disabled or powered off, the driver outputs present a high-impedance to the bus for reduced system loading. The SN75LBC174A is characterized for operation over the temperature range of 0°C to 70°C. The SN65LBC174A is characterized for operation over the temperature range of −40°C to 85°C.
