The Intersil 82C82 is a high performance CMOS Octal
Latching Buffer manufactured using a self-aligned silicon
gate CMOS process (Scaled SAJI IV). The 82C82 provides
an eight-bit parallel latch/buffer in a 20 pin package. The
active high strobe (STB) input allows transparent transfer of
data and latches data on the negative transition of this sig-
nal. The active low output enable (OE) permits simple inter-
face to state-of-the-art microprocessor systems.

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:
I = CL(dv/dt)
(EQ. 1)
Assuming that all outputs change state at the same time and
that dv/dt is constant;
I = CL
(EQ. 2)
(---V----C----C-t--R---x-/--t-F-8---0----%------)
(EQ. 3)
where tR = 20ns, VCC = 5.0V, CL = 300pF on each of eight
outputs.
I = (8 x 300 x 10-12)x (5.0V x 0.8)/(20 x 109) = 480mA (EQ. 4)
This current spike may cause a large negative voltage spike
on VCC, which could cause improper operation of the device.
To filter out this noise, it is recommended that a 0.1µF
ceramic disc decoupling capacitor be placed between VCC
and GND at each device, with placement being as near to
the device as possible.
