LTC6915 Timing Requirement of Hold Thru pin

Nishimoto

on Oct 7, 2020

Hi,

My customer and I could not find any timing requirement of Hold Thru pin.

In order to implement MCU firmware, They would like to know how long shoud wait after changing hold thru pin level and access CLK and D3:D0.

We look forward to hearing from you as soon as possible.

Thanks.

Nishimoto.

Hi Nishimoto,

I've already relayed this question to the product owner and will get back to you as soon as possible. Quick follow up question though, do you have a target waiting time for the hold thru pin?

Thanks,

Donnie

Hi Nishimoto,

Once the HOLD_THRU pin goes high, then the control bits (D3:D0) are latched internally inside the LTC6915 with no delay.

Hope this answers your question!

Thanks,

Donnie
