Frequently Asked Questions
What communication standards does the AM26LS33ACDRE4 support?
The AM26LS33ACDRE4 supports EIA-422-B, TIA-422-B, EIA-423-B, TIA-423-B, V.10, and V.11 interface standards. These balanced differential standards enable reliable data transmission over long cable runs in industrial environments, with the RS-422 standard supporting data rates up to 10Mbps and cable lengths up to 1200 meters at lower data rates.
How many receiver channels does the AM26LS33ACDRE4 have and what is the output type?
The AM26LS33ACDRE4 contains 4 independent line receiver channels (quad configuration), each with 3-state output capability. The 3-state outputs allow multiple receivers to share a common data bus by tri-stating inactive receivers, with a minimum output swing of 2.25V and maximum high-level input current of 20µA (0.00002A).
What package does the AM26LS33ACDRE4 come in?
The AM26LS33ACDRE4 is housed in an R-PDSO-G16 package (16-pin plastic dual small outline), commonly known as a 16-pin SOIC. The E4 suffix indicates tape-and-reel packaging optimized for high-volume automated surface-mount assembly. The JESD-609 code e4 confirms lead-free, RoHS-compliant construction.
What are the input characteristics of the AM26LS33ACDRE4?
The AM26LS33ACDRE4 features differential Schmitt trigger inputs, which provide enhanced noise immunity by introducing hysteresis into the input switching threshold. This characteristic makes the receiver highly resistant to noise, reflections, and ground potential differences on long cable runs, ensuring clean output signals even in electrically noisy industrial environments.
What are typical applications for the AM26LS33ACDRE4?
Typical applications include RS-422 serial communication interfaces for CNC machines, industrial robots, and PLC networks; distributed control system data links; multi-drop RS-422 bus receivers in factory automation; telecommunications line interfaces; and scientific instrumentation requiring differential signal reception. The quad configuration allows a single IC to receive data from four independent RS-422 transmitters.
