Application Information
Decoupling Capacitors
The transient current required to charge and discharge the
300pF load capacitance specified in the 82C82 data sheet is
determined by:
Assuming that all outputs change state at the same time and
that dv/dt is constant;
where tR = 20ns, V
CC
= 5.0V, C
L
= 300pF on each of eight
outputs.
This current spike may cause a large negative voltage spike
on V
CC
, which could cause improper operation of the device.
To filter out this noise, it is recommended that a 0.1
μ
F
ceramic disc decoupling capacitor be placed between V
CC
and GND at each device, with placement being as near to
the device as possible.
