Recommended Operating Condition Device Selection Guide 1 Absolute Maximum Ratings 1, 2 Notes: 1. For other options of Multiturn Encoder Module, please refer to factory. Notes: 1. Internal hardware clock that is built into the module 2. As unique coded gear-wheels techniques are implemented to generate unambiguous positional information, the interactions between these high wear resistant gear wheels are subjected to mechanical wear and tear. Notes: 1. Stresses greater than those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. 2. Exposure to absolute maximum rating conditions for extended periods may affect reliability. 3. This device meets the ESD ratings of the IEC61000-4-2 Level 1 (2KV).

- Only applicable for STROBE output.
- Only applicable for MSBINV input.
- RS-422 differential line driver for DATA output.
- RS-422 differential line receiver for SRCLK input.
- Only applicable for MSBINV input.
- SRCLK low-time = 0.50/fSRCLK; high-time = 0.50/fSRCLK.
- Refer to Figure 4 for timing description.
- Valid data on falling edges of SRCLK with STROBE is high.
