JEDEC – ICCH is the current into a supply terminal of an integrated circuit when the output is (all outputs are) at a high-level voltage. ICCL is the current into a supply terminal of an integrated circuit when the output is (all outputs are) at a low-level voltage.

TI – The current into the VCC supply terminal of an integrated circuit.

This parameter is the current into the VCC supply terminal of an integrated circuit under static no-load conditions. ICC is tested by applying the specified VCC level and measuring the current into the device.

The outputs of the device are left open, while all inputs—control and data—are biased to either VCC or GND. For CMOS technologies, this is done to eliminate any current that may be caused by any input conditions or output loads.
