What are the key features of AM26C32CDB?
- Quad differential Schmitt trigger inputs with ±7 V common-mode range and 60 mV hysteresis for robust noise immunity on long cable runs
- Compliant with EIA-422-B, TIA-422-B, EIA-423-B, V.10, and V.11 standards enabling use in a wide range of industrial serial communication interfaces
- ±200 mV differential input sensitivity supports reliable signal detection in electrically noisy industrial and RS-422 transmission line environments
- 16-pin SOIC (R-PDSO-G16) small-outline package minimizing PCB footprint while housing 4 fully independent line receiver channels
What is AM26C32CDB used for?
The AM26C32CDB is used in industrial RS-422 and RS-423 serial communication systems where multiple differential signal channels must be received reliably over long cable runs in electrically noisy environments. Its quad channel architecture makes it well-suited for motor drive feedback interfaces, CNC machine control links, and data acquisition front-ends requiring simultaneous multi-channel differential reception. The wide ±7 V common-mode range also accommodates ground potential differences between transmitter and receiver systems in distributed industrial installations.

Frequently Asked Questions
What standards does the AM26C32CDB comply with and what are its input sensitivity characteristics?
The AM26C32CDB complies with EIA-422-B, TIA-422-B, EIA-423-B, TIA-423-B, V.10, and V.11 differential signaling standards. It features a ±200 mV minimum differential input sensitivity and ±7 V common-mode voltage range with 60 mV typical input hysteresis, ensuring reliable signal detection even in high-noise industrial environments with significant ground potential differences between nodes.
How many receiver channels does the AM26C32CDB provide and which package is used?
The AM26C32CDB contains 4 independent differential line receiver channels housed in a 16-pin SOIC (R-PDSO-G16) package. Each channel uses a Schmitt trigger input architecture, enabling the quad receiver to handle 4 simultaneous RS-422 differential signal lines with a minimum output swing of 2.4 V, making it efficient for multi-channel industrial communication boards.
In which industrial communication scenarios is the AM26C32CDB most effectively deployed?
The AM26C32CDB is particularly effective in RS-422 point-to-point and multi-drop communication links found in factory automation, CNC control systems, and SCADA networks. Its ±7 V common-mode tolerance handles the ground voltage differences common between control cabinets and remote sensors or actuators, while the 4-channel design allows a single IC to receive data, clock, and handshaking signals simultaneously on cables extending up to several hundred meters.
What is the significance of the 60 mV input hysteresis in the AM26C32CDB for noise-prone applications?
The 60 mV typical input hysteresis in the AM26C32CDB means the receiver requires the differential input signal to cross separate positive and negative thresholds before toggling output state, preventing false triggering caused by noise or signal reflections on long RS-422 cable runs. This hysteresis is especially valuable in industrial environments where electromagnetic interference can induce millivolt-level noise on differential pairs, keeping output logic stable without additional filtering components.
