Frequently Asked Questions

How many receiver channels does SN75ALS173NE4 provide, and what interface standards does it support?

The SN75ALS173NE4 integrates 4 independent differential receiver channels, supporting RS-422, RS-423, EIA-485, V.10, V.11, X.26, and X.27 standards, making it suitable for a broad range of industrial serial communication protocols.

What output drive capability does SN75ALS173NE4 offer for bus-sharing applications?

The SN75ALS173NE4 provides 3-state outputs with a maximum output low current of 8 mA, allowing multiple receivers to share the same RS-485 bus in multi-drop configurations without driving conflicts.

Which industrial automation designs benefit from the Schmitt-trigger inputs on SN75ALS173NE4?

Designs exposed to electrical noise, long cable runs, or ground potential differences—such as PLC networks, motor drive feedback links, and factory instrumentation—benefit from the Schmitt-trigger inputs, which provide hysteresis to reject glitches on RS-422 and RS-485 differential lines spanning hundreds of meters.

Is SN75ALS173NE4 RoHS-compliant, and what does the 'E4' suffix indicate?

Yes, SN75ALS173NE4 carries the JESD-609 code 'e4', confirming the device is lead-free and RoHS-compliant, with the E4 suffix specifically denoting the green/halogen-free, Pb-free package variant used in Texas Instruments' environmentally responsible product line.
