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 mF for every

five isolators used. Place the capacitor as close as possible to the

clock driver.
