You can drive signals into the I/O pins and GCLK[3..0] pins of MAX V devices before
or during power up or power down without damaging the device. To simplify the
system-level design, MAX V devices support any power-up or power-down sequence
(V
A device that does not support hot socketing may interrupt system operation or cause
contention by driving out before or during power up. In a hot-socketing situation, the
MAX V device’s output buffers are turned off during system power up. MAX V
devices do not drive out until the device attains proper operating conditions and is
fully configured. For more information about turn-on voltages, refer to
Reset Circuitry” on page
MAX V devices do not have a current path from the I/O pins or GCLK[3..0] pins to
the V
be inserted into (or removed from) a system board that is powered up without
damaging or interfering with system-board operation. When hot socketing, MAX V
devices may have a minimal effect on the signal integrity of the backplane.
You can power up or power down the V
sequence. During hot socketing, the I/O pin capacitance is less than 8 pF. MAX V
devices meet the following hot-socketing specifications:

MAX V devices are immune to latch-up when hot socketing. If the TCK JTAG input pin
is driven high during hot socketing, the current on that pin might exceed the
specifications listed above.
I
when the device is being powered up or powered down. This specification takes into
account the pin capacitance but not the board trace and external loading capacitance.
You must consider additional capacitance for trace, connector, and loading separately.
The peak current duration due to power-up transients is 10 ns or less.
The DC specification applies when all V
powered-up or powered-down conditions.
