1. This is the standby current when CLK_EN is high.

2. Data buses will have a +50µA leakage current when RESET is high due to the pull-down device.

During AC testing, inputs are driven at 0.4V and 2.4V levels. Unless othrewise

specified, switching times are measured from the 1.5V level of DCLK to the 0.8V

or 2.0V levels at the input/output.
