max. I
BHL
should be measured after lowering V
IN
to GND and
then raising it to V
IL
max.

min. I
BHH
should be measured after raising V
IN
to V

and
then lowering it to V

An external driver must source at least I
BHLO
to switch this node from low to high.

High-impedance state during power up or power down
This is the increase in supply current for each input that is at the specified TTL voltage level rather than V
CC
or GND.
