  Resolved

  Part Number: SN74LV595A Hi team, For the the 3.3V operation, the datasheet specifies a minimum hold time of 1.5ns but the SRCLK to QH' has minimum time of 1ns. If we are connecting output of one to the input of another, could this violate the minimum hold…

  Adrian Thewlis

  Resolved

  Part Number: SN74LV595A-EP The data-sheet says that the thermal pad should be connected to the correct circuit, but I can't find anything that says what that is. My guess is ground, which would make sense for a thermal plane. But I have run into at least…
