MAX 7000AE, MAX 7000B, & MAX 3000A Devices
Workaround
If an output pin driving a low going pulse during power-up in
MAX 7000AE and MAX 3000A devices is an issue for your system, there
are a few possible workarounds.
■ Usually a low going pulse is only an issue for a device on the board
that is expecting a pull-up value. The MAX device pulse may pull
down the pulled-up signal either partially or totally depending on
how fast the V
CCINT
ramp rate is with respect to the numbers in
Table 4. A stronger pull-up resistor can be used to maintain the high
value. The pull-up should be chosen such that no more than 24 mA
is sunk by a MAX device I/O pin.
■ For V
CCINT
rise time faster than the times shown in Table 4, a
MAX 7000B device can be used as an alternative since its rise times
shown in Table 5 are much faster. MAX 7000B device use a 2.5-V
V
CCINT
supply and are pin compatible with MAX 7000AE devices.
■ Use a V
CCINT
supply with rise time slower than number shown in
Table 4 for MAX 7000AE, MAX 3000A devices.
