  • TSS721A: TSS721A

    TI Thinks Resolved
    Part Number: TSS721A Hello, About the usage of TSS721A, the datasheet Page4 described like this: "Beacause the TSS721A is configured for half-duplex only, the current modulation from RX or RXI is repeated concurrently as ECHO on the outputs TX and…

  • TSS721A: TSS721A - Interrupt routine after falling edge -- Root cause / corrective action requested

    TI Thinks Resolved
    Part Number: TSS721A If a falling edge is sent from the external M-Bus master to the TSS721A, the voltage on pin PF (pin 5) will break down to 1.4 V for about 5 μs. This voltage in turn causes an interrupt routine to be triggered in our microcontroller…
