About RS422/RS423 Receivers

Differential line receivers like the DS26C32ATN/NOPB are fundamental to noise-resistant data transmission over long distances. By comparing voltage differences between paired signal lines, they reject common-mode interference from motors, power surges, or EMI – a critical capability in factory floors or harsh electrical environments where single-ended interfaces fail.

These components enable reliable communication in multi-point networks and point-to-point links. RS422/RS423 standards remain vital in legacy industrial systems, medical devices, and infrastructure where upgrading entire architectures is impractical. Selecting high-quality receivers ensures signal integrity, reduces error rates, and extends equipment lifespan.

Packaging

Available in protective Tube packaging for secure handling and storage. PCX manages all logistics to prevent damage during transit.

Frequently Asked Questions

Question: Is this IC still usable despite being obsolete?
Answer: Absolutely. PCX maintains stock for repair and lifecycle extension. We verify functionality to ensure performance matches original specifications.

Question: What is the significance of 60mV hysteresis?
Answer: Hysteresis prevents output oscillation near threshold voltages by creating a “dead zone,” enhancing noise immunity in electrically noisy environments.

Question: Can this receiver handle RS485 signals?
Answer: No. While electrically similar, RS485 requires different fail-safe biasing. Use dedicated RS485 receivers for that standard.

Question: What cable lengths are supported?
Answer: Typical RS422 links achieve 1200m at 100kbps. Actual range depends on cable quality, baud rate, and noise levels – consult the datasheet for design guidance.

Question: How does PCX ensure genuine Texas Instruments parts?
Answer: We source exclusively through authorized channels and perform batch-level traceability checks, eliminating counterfeit risks.

Question: Is termination required for this receiver?
Answer: Yes. RS422 networks require a termination resistor (typically 120Ω) at the receiver end to prevent signal reflections.
