●The SN65LBC173A and SN75LBC173A 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, 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.
●The SN75LBC173A is characterized for operation over the temperature range of 0°C to 70°C. The SN65LBC173A is characterized over the temperature range from -40°C to 85°C
● Designed for TIA/EIA-485, TIA/EIA-422, and ISO 8482 Applications
● Signaling Rate Exceeding 50 Mbps
● Fail-Safe in Bus Short-Circuit, Open-Circuit, and Idle-Bus Conditions
● ESD Protection on Bus Inputs Exceeds 6kV
● Common-Mode Bus Input Range -7 V to 12 V
● Propagation Delay Times <16 ns
● Low Standby Power Consumption <20 µA
● Pin-Compatible Upgrade for AM26LS32, DS96F173, LTC488, and SN75173
●LinBiCMOS is a trademark of Texas Instruments.
●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).
