The bypass capacitors should include a 0.1μF ceramic
surface-mount capacitor between each supply pin and
the ground plane, located as close to the package as
possible. Optionally, place a 10μF tantalum capacitor
at the power-supply pins
points of entry to the PC
board to ensure the integrity of incoming supplies. The
power-supply trace should lead directly from the tanta-
lum capacitor to the V
CC
and V
EE
pins. To minimize
parasitic inductance, keep PC traces short and use
surface-mount components.
Use surface-mount resistors for input termination and
output back termination. Place the termination resistors
as close to the IC as possible.
