NOTES:

1. V

DD

must be lowered to 0.2 V in order to reset part.

2. Each I/O must be externally limited to a maximum of 25 mA and each octal (I/O0.0 to I/O0.7 and I/O1.0 to I/O1.7) must be limited to a

maximum current of 100 mA for a device total of 200 mA.

3. The total current sourced by all I/Os must be limited to 160 mA.
