*Current consumption under the
disable function should be

3) Condition
(1) Oscilloscope
· Band width should be minimum 5 times higher (wider) than measurement frequency.
· Probe earth should be placed closely from test point and lead length should be as short as possible
* Recommendable to use miniature socket. (Donât use earth lead.)
(2) L_CMOS also includes probe capacitance.
(3) By-pass capacitor (0.01 µF to 0.1 µF) is placed closely between VCC and GND.
(4) Use the current meter whose internal impedance value is small.
(5) Power supply
· Start up time (0 %VCC to 90 %VCC) of power source should be more than 150 µs.
· Impedance of power supply should be as lowest as possible.
