-0.2 V and V
IL
max = 0.5 V with all
output pins unloaded and the on-chip pull-up MOS in the off state.

4. I
CC
depends on V
CC
and f as follows:
I

Notes: 1. To protect chip reliability, do not exceed the output current values in table 22-13.
2. When driving a darlington pair or LED directly, always insert a current-limiting resistor in the output line, as show
in figures 22-33 and 22-34.
