ADG1414: Must -RESET/VL connect to power supply?

We are using many ADG1414 switches and have daisy-chained the serial interfaces.  We connected the -RESET/VL to an active-low logic signal for use as -RESET but not to a power supply.  The daisy chain is not functioning past the second or third device in the chain and I suspect the VL pin needs an actual power supply.  How much power does this pin draw worst-case?  If I add a 1K pullup to the logic power supply, will that provide sufficient current so that I can still pull the signal low via the logic signal for -RESET?
