Frequently Asked Questions
How many differential driver channels does the SN75174DW have?
The SN75174DW integrates four independent differential line driver channels in one SOIC-16 package. Each channel accepts a TTL/CMOS logic input and produces complementary differential outputs compliant with RS-422 and RS-423 electrical standards, making it ideal for multi-channel balanced serial links.
What supply voltage and data rate does the SN75174DW support?
The SN75174DW operates from a single 5 V supply and supports data rates up to 10 Mbps. The differential output architecture provides high noise immunity, making it suitable for long-cable industrial environments where single-ended signals would be degraded by ground noise or EMI.
Which applications commonly use the SN75174DW?
Typical applications include RS-422 multi-drop industrial buses, PLC-to-sensor serial links, CNC machine control, data acquisition frontends, and telecom equipment backplanes. Its quad-channel density reduces BOM count, and the SOIC-16 footprint simplifies layout compared to single-driver alternatives.
What are common pin-compatible or functionally equivalent alternatives to the SN75174DW?
Pin-compatible alternatives include the AM26LS31 quad RS-422 driver (same SOIC-16 footprint and RS-422 compliance). The SN65174 is the industrial-temp version (−40°C to +85°C) of the same device. MAX491 and MAX3491 are also functionally compatible RS-422 driver/receiver combos for designs that need both functions on one chip.
Is the SN75174DW RoHS compliant and what does the package suffix mean?
Yes, the SN75174DW is RoHS compliant and available in a lead-free (Pb-free) version. The D suffix denotes the SOIC package family, and W specifies the wide-body (7.5 mm) 16-pin variant. This wide-body SOIC-16 is sometimes listed as SOIC-16W or SO-16W in BOM tools.
