Frequent Questions

  • [FAQ] What is the default output of a latched device? (Flip-Flop, latch, register)

    FAQ: Logic and Voltage Translation > Output Parameters >> Current FAQ Flip-flops, latches, and registers do not have a default state on power up. The output is in an 'unknown' state until data is clocked through. Because of this, SPICE simulation models…

  • [FAQ] How does a slow or floating input affect a CMOS device?

    FAQ: Logic and Voltage Translation > Input Parameters >> Current FAQ There are two primary issues associated with slow and floating inputs. Not sure what a 'floating input' is? Please see our FAQ: What is a floating input or floating node? (1) Shoot…

  • [FAQ] CCS: Where can I download previous versions of Code Composer Studio?

    Tool/software: Code Composer Studio Where can I download old versions of: Code Composer Studio Compilers Code Composer

  • [FAQ] Compiler/MSP430FR2522: Missing “Workaround specified silicon errata” [CPU21], [CPU22] and [CPU40] compiler flags for MSP430FR2522, MSP430FR2422 and MSP430FR2512 devices in Code Composer Studio and IAR embedded workbench.

    Part Number: MSP430FR2522 Tool/software: TI C/C++ Compiler Of particular importance, CPU40 causes assembler instructions to be skipped, potentially causing unpredictable behavior. Refer to the device’s errata document for details on these silicon issues…

  • [FAQ] If the OE pin is asserted to maintain Hi-Z at the IO, will it disconnect the internal pull-up resistors in TXS devices?

    FAQ: Logic and Voltage Translation > Voltage Translators >> Current FAQ Yes, the internal pull-up resistors are disconnected once OE is asserted(to enable High impedance on the IO ports) Additionally, if the device supports Vcc isolation feature …
