• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.

• The Voltage and waveform of CSP (Chip size package)
cannot be measured, because its lead layout is different
surface
from that of conventional IC.
