What are the key features of AM26C32CNS-P?
- Four independent differential receivers in a single 16-pin package reduce component count and board space in RS-422 and RS-423 multi-channel data links
- Wide common-mode input voltage range of -7 V to +7 V ensures robust noise immunity in industrial and long-distance cable environments
- Complies with EIA/TIA-422-B and EIA/TIA-423-B standards, enabling interoperability with all RS-422 and RS-423 transmitters
- 3-state output enable per receiver allows bus arbitration and multiplexing in multi-drop communication systems
What is AM26C32CNS-P used for?
The AM26C32CNS-P is used in industrial RS-422 communication links, CNC machine tool interfaces, and programmable logic controller (PLC) serial ports where differential signaling provides immunity to common-mode noise over cable runs of up to 1200 meters. Its quadruple configuration in a single 16-pin SOIC suits multi-axis encoder feedback lines, digital audio AES/EBU interfaces, and data acquisition systems that require four independent differential-to-TTL conversions. The wide common-mode range also makes it reliable in electrically noisy factory floor environments with large ground potential differences between nodes.

Frequently Asked Questions
How many differential receiver channels does the AM26C32CNS-P integrate, and what supply voltage does it require?
The AM26C32CNS-P integrates 4 independent differential receiver channels in a single 16-pin SOIC package, operating from a single 5 V supply. This quad configuration allows a designer to terminate four RS-422 or RS-423 differential pairs without additional ICs, reducing component count and simplifying PCB layout for multi-channel serial communication boards.
What common-mode voltage range does the AM26C32CNS-P tolerate in noisy industrial cable environments?
The AM26C32CNS-P tolerates a common-mode input voltage range of -7 V to +7 V, which covers the ground potential differences typically encountered in industrial RS-422 networks spanning hundreds of meters. This wide range ensures correct logic-level output even when cable shields are imperfectly grounded or when heavy machinery induces common-mode noise on the differential pair.
Can the AM26C32CNS-P be used in multi-drop RS-422 bus configurations?
Yes. Each of the 4 receiver channels features a 3-state output enable pin that places the output in a high-impedance state when deasserted. In a multi-drop RS-422 bus with up to 32 unit loads, multiple AM26C32CNS-P devices can be connected in parallel with their outputs tied together, and only the addressed receiver's output is enabled at any given time, preventing bus contention.
How does RS-422 differential signaling on the AM26C32CNS-P compare to a standard UART for long cable runs?
RS-422 differential signaling, as implemented by the AM26C32CNS-P, can reliably transmit data at 100 kbps over cable lengths up to 1200 meters or at 10 Mbps over 12 meters. A standard single-ended UART signal is limited to roughly 15 meters at low baud rates before capacitive loading and noise degrade signal integrity, making RS-422 far superior for long-distance industrial communication links.
