  • TIDA-00580: Reduction of several TTL/RS422 incremental/quadrature encoder signals on the collector board for transport to FPGA/Microchip

    TI Thinks Resolved
    Part Number: TIDA-00580 Other Parts Discussed in Thread: SN74HC165 Which possibilities exist to merge signals of >=4 incremental/quadrature Encoders with following signals: 2x TTL A B Z [optional] Err 2x RS422 A A^ B B^ Z Z^ [optional] Err Which…

  • RE: 74AC11257: Potential cross for HCTL-2022?

    Resolved
    TI does not make a similar device. A quadrature decoder can be implemented in hardware with several logic devices (TIDA-00580), or in software ( SLAA795 ). Some microcontrollers (TMS320, C2000) can have a built-in quadrature decoder module.

  • RE: TIDA-00175:

    Dear Amod, Thank you for checking with TI. We won't have a drop-in replacement,.but our C2000 Microcontrollers offers an integrated quadrature decoder module (eQEP) for use with e.g. incremental encoders. The eQEP interfaces directly with linear or…
