SN65LBC174A-EP 增强型产品四路 Rs-485 差动线路驱动器
The SN65LBC174A–EP is a quadruple differential line driver with 3–state outputs, designed for TIA/EIA–485 (RS–485), TIA/EIA–422 (RS–422), and ISO 8482 applications.
This device is optimized for balanced multipoint bus transmission at signaling rates up to 30–million bits per second (Mbps). 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.
Each driver features current limiting and thermal–shutdown circuitry, making it suitable for high–speed multipoint applications in noisy environments. The device is designed using LinBiCMOSTM technology, facilitating low power consumption and robustness.
The two enable (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 SN65LBC174A–EP is characterized for operation over the temperature range of –55°C to 125°C
