Caution: These CMOS devices have input static
protection (Class 2) but are still susceptible to
damage when exposed to extremely high static
electrical charges.

28-LINE DECODER/DRIVER
Intended for use in ink-jet printer applications, the A6817SEP
addressable 28-line decoder/driver combines low-power CMOS inputs
and logic with 28 high-current, high-voltage bipolar outputs. A 4-to-14
line decoder determines the selected output driver (n) in each
14-driver bank. Two independent output-enable inputs (active low)
then provide the final decoding to activate 1- or 2-of-28 outputs
