Hi Team,

For our HD3SS3212, can you share the delay from transitioning between Operational to Shutdown mode when OEn is high?

Also the delay from Shutdown to Operational?

Didn't see this spec in our datasheet.

Best Regards,

Joey

Hello Joey,

The definition is a little bit ambiguous but it's there, please see page 7 for Tsw_on & Tsw_off, both values are0.5us.

Regards,
Diego.

Hi Diego,

From Page 7, my understanding is that this spec is only for switching on the SEL pin between A to B or A to C.

What I'm looking for is the time on the OEn pin from Operational to Shutdown and vice versa.

Thanks ,Joey

Joey,

It applies for OEn pin as well; SEL pin will deactivate one path, meanwhile OEn deactivates both, so the timing is similar in both cases.

Regards,
Diego.
