SN74HCS365: Overcurrent

Part Number: SN74HCS365

Hi Team,

According to datasheet Maximum Icc is 2 µA.
The customer is using it on 3.3V, the current of bare chip test has 50 ~ 200µA fluctuation, and 3mA under 6V.
Even if it is not connected to OE and IO, and only connected to the power supply pin, the power consumption is still very high.
What are the test conditions for 2 µA?
Is it according to Figure 6-3 and Figure 6-4 on datasheet?

    Hey Tom,

    The conditions for Icc are listed with the spec. To clarify them, all inputs have a valid logic state (Vcc or GND). This is important since floating nodes can cause increase supply current. This might be the case if only the Vcc pin is connected. Secondly, there should be no output current (Io = 0) as this will be coming from the supply in the High output state.
