Frequently Asked Questions
What interface standards does the ISO35TDWR support?
The ISO35TDWR supports both EIA-485 (RS-485) and EIA-422 (RS-422) interface standards. It operates as a single-channel line transceiver with differential signaling, making it compatible with multi-drop RS-485 bus topologies and point-to-point RS-422 connections commonly used in industrial control systems.
What is the maximum data rate supported by the ISO35TDWR?
The ISO35TDWR supports data rates up to 250kbps, which is the standard maximum rate for RS-485 transceivers at full cable length. For shorter cable runs, higher data rates may be achievable. The differential Schmitt trigger input ensures reliable operation even at maximum speed in noisy industrial environments.
What package does the ISO35TDWR come in and what are its dimensions?
The ISO35TDWR is housed in a 16-Pin SOIC (Small Outline Integrated Circuit) package, identified by JESD-30 code R-PDSO-G16. This surface-mount package is compact and suitable for PCB designs with limited space. It is also RoHS compliant (Pb-free, JESD-609 code e4) for use in environmentally regulated applications.
What are typical applications for the ISO35TDWR?
The ISO35TDWR is commonly used in industrial automation, PLC communications, building management systems, motor drive interfaces, and HVAC control networks. Its robust differential signaling over RS-485/RS-422 makes it ideal for multi-node bus architectures in factory environments where long cable runs and electrical noise are significant concerns.
