GENERAL DESCRIPTION
The AD246 is a compact, inexpensive clock driver that can be
used to obtain the required clock from a single 15 V supply.
The
circuit shown in Figure 1 (essentially an AD246)
can operate at
least 32 AD204s at the rated minimum supply voltage of 14.25 V
and
one additional isolator can be operated for each 40 mV
increase in supply voltage up to 15 V.
A supply bypass capacitor is included in the AD246, but if many
AD204s are operated from a single AD246, an external bypass
connector should be used with a value of at least 1
m
F for every
five isolators used. Place the capacitor as close as possible to the
clock driver.
