SYSTEM STARTUP
(figure2)
It is not mandatorythat V
S
is present before V
CC
.
With the presence of the V
CC
the internal logic
would be reseted and the system restarts under
control of the inputs. If CSN = 0 for more than
100
μ
s after the presence of V
CC
the standby
mode is activated.Standby is alsoactivated when
the CSN and VCC would be high at the same
time. When CSN = 0 and V
CC
goes up, the device
is not controlledby the bus. The outputs remainin
tristate but the current consumption is larger than
100
μ
A. A high - low - signal at the CSN - wire is
mandatory to control the outputs. There is no un-
dervoltage detection level for the supply voltage
VS implemented. The VCC should be supplied
from the same voltage supply as the driver of the
D0 -D3 pins (eg.
μ
C).
