PRODUCTION DATA. SN65LBC173A-EP SLLSEH1 – NOVEMBER 2016 SN65LBC173A-EP Quadruple RS-485 Differential Line Receiver 1 (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). . 1 Features 1 • Designed for TIA/EIA-485, TIA/EIA-422 and ISO 8482 Applications • Signaling Rates (1) up to 50 Mbps. • Fail-Safe in Bus Short-Circuit, Open-Circuit, and Idle-Bus Conditions • ESD Protection on Bus Inputs Exceeds 6 kV • Common-Mode Bus Input Range –7 V to 12 V • Propagation Delay Times < 18 ns • Low-Standby Power Consumption < 32 µA • Pin-Compatible Upgrade for AM26LS32, DS96F173, LTC488, and SN75173 2 Applications • Supports Defense, Aerospace, and Medical Applications – Controlled Baseline – One Assembly and Test Site – One Fabrication Site – Extended Product Life Cycle – Extended Product-Change Notification – Product Traceability 3 Description The SN65LBC173A is a quadruple differential line receiver with tri-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. The G and G inputs provide enable control logic for either positive- or negative-logic enabling all four drivers. When disabled or powered off, the receiver inputs present a high-impedance to the bus for reduced system loading.
