TCAN334G: standby & shutdown preference

Part Number: TCAN334G
Other Parts Discussed in Thread: TCAN334

I want to use TCAN334G with standby & shutdown mode.

I have a question about standby & shutdown preference

After TCAN334 was standby mode(8pin is high), SHDN is high(5pin is high) => TCAN is shutdown mode?

After TCAN334 was shutdown mode(5pin is high), STB is high(8pin is high) => TCAN is still shutdown mode?

if STB & SHDN is high at the same time, TCAN is stanby mode or shutdown mode?

Thanks in advance.

    Hi Seungwook, 

    The Shutdown pin has priority over the standby mode of the device. If both the STB pin and the SHDN pin are held high, the device will be in shutdown mode with the driver and receiver disabled. Toggling the STB pin while the device is already in shutdown mode (SHDN = high) will have no impact on the device state. 

    Let me know if you have any more questions. 

    Regards,
