current

1.VDD must be lowered to 0.2V for at least 50µs in order to reset part.

2.Each I/O must be externally limited to a maximum of 25 mA and each octal (IO0_0 to IO0_7 and IO1_0 to IO1_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.
