Note: The above decoupling capacitor arrangement shown is recommended to maximize the benefits of
the internal split ground system. Capacitor values between 0.01 and 0.1JlF' should provide adequate
noise isolation. Because of the number of high current drivers on the 53C81 0, a multi-layer PC board
with power and ground planes is required.
