Frequently Asked Questions
What interface standards does AM26C32INS support and at what data rate?
The AM26C32INS is compliant with EIA-422-B, EIA-423-B, V.10, and V.11 differential interface standards, supporting data rates up to 10 Mbps over twisted-pair cables. Its Schmitt-trigger differential inputs maintain signal integrity even with common-mode noise up to ±7 V on the line.
How many receiver channels does AM26C32INS provide and what package is used?
The AM26C32INS integrates 4 independent differential line receiver channels in a 16-pin SOIC package, allowing a single chip to receive all 4 data lines of a multi-channel RS-422 bus. The SOIC footprint simplifies board layout compared to DIP alternatives in high-density industrial designs.
What maximum cable length can AM26C32INS reliably receive data from?
Using balanced differential signaling per EIA-422-B, the AM26C32INS can reliably receive data from cables up to 1200 m at low data rates (below 100 kbps) or up to 12 m at the maximum rate of 10 Mbps, providing flexibility for both long-distance and high-speed RS-422 industrial links.
How does AM26C32INS compare to SN75C1168 for new RS-422 designs?
Both devices offer quad RS-422 line receivers, but AM26C32INS is pin-compatible with the industry-standard AM26C32 family, making it a direct drop-in replacement in legacy designs. For new 3.3 V systems requiring lower power consumption of under 10 mA supply current, parts like SN65HVD05 with 3.3 V operation may be preferred, while AM26C32INS suits 5 V designs needing proven long-term availability.
