Frequently Asked Questions

What communication standard does the SN75LBC184D support?

The SN75LBC184D supports EIA-485, TIA-485, and ISO 8482 standards, making it compatible with RS-485 and RS-422 multi-drop serial bus applications. These standards allow up to 32 unit loads on a single bus, enabling multi-node industrial communication networks over distances of up to 1200 meters.

What is the supply voltage of the SN75LBC184D and what input type does the receiver use?

The SN75LBC184D operates from a 5 V supply. Its receiver features differential Schmitt trigger inputs, which provide hysteresis to reject noise and glitches on the RS-485 bus, ensuring reliable data reception in electrically noisy industrial environments.

What package does the SN75LBC184D come in and how many pins does it have?

The SN75LBC184D is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package, designated JESD-30 code R-PDSO-G8. This compact surface-mount package simplifies PCB layout and is widely available, making it easy to integrate into industrial communication designs.

Can the SN75LBC184D be used in half-duplex RS-485 networks?

Yes, the SN75LBC184D is designed for half-duplex RS-485 communication, with a single differential driver and receiver sharing the bus lines. A direction control pin allows the host controller to switch between transmit and receive modes, making it ideal for multi-drop networks used in building automation and industrial control systems.
