4.Test circuit
1) Waveform observation
2) Current consumption
*Current consumption under the
disable function should be
= GND.
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. (Don’t use earth lead.)
(2) L_CMOS also includes probe capacitance.
(3) By-pass capacitor (0.01 mF to 0.1 mF) 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 ® 90 %VCC) of power source should be more than 150 ms.
· Impedance of power supply should be as lowest as possible.
