NOTES:
1.
The
only
requirement
for
the
sequence 'of
applying
voltage
to
the device
is
that
VOO,
VCC,
and
VSS
should never be .3V
more
negative
than
VSS.
2.
Typical
values are
for
TA
= 25°C and nominal
power
supply voltages.
3. The I
DO
and
ICC
currents
flow
to
VSS'
The I
Be
current
is
the sum
of
all leakage currents.
4.
During
CE
on
VCC
supply
current
is
dependent
on
output
loading,
VCC
is
connected
to
output
buffer
only.
