Power Supply Decoupling
PCB Pad Layout
NOTES: A. All linear dimensions are in millimeters.
The LUMENOLOGY r Company
The power supply lines must be decoupled with a 0.1-μF capacitor placed as close to the device package as
possible. The bypass capacitor should have low effective series resistance (ESR) and effective series
inductance (ESI), such as the common ceramic types, which provide a low impedance path to ground at high
frequencies to handle transient currents caused by internal logic switching.
Suggested PCB pad layout guidelines for the CL package is shown in Figure 8.
