These are stress ratings only. Functional operation of
this device at these or any other conditions above
those indicated in the operational sections of these
specification is not implied or intended. Exposure to
the absolute maximum rating conditions for extended
periods may affect device reliability.

Extended Range Devices
1. Minimum DC voltage on input or I/O pins is -0.5V.
During voltage transitions, input or I/O pins may
undershoot VSS to -2.0V for periods of up to 20ns.
Maximum DC voltage on input and I/O pins is VCC
+0.2V. During voltage transitions, input or I/O pins may
overshoot to VCC +2.0V for periods up to 20ns.

VSS to -2.0V for periods of up to 20ns. Maximum DC
input voltage on A9 is +12.5V which may overshoot to
14.0V for periods up to 20ns.
3. No more than one output is shorted at a time. Duration
of the short circuit should not be greater than one
second.
execute the command. The contents of the register serve
as inputs to the internal state machine. The state machine
outputs dictate the function of the device. The appropriate
device bus operations table lists the inputs and control
levels required, and the resulting output. The following
subsections describe each of these operations in further
detail.
Device Bus Operations
This section describes the requirements and use of the
device bus operations, which are initiated through the
internal command register. The command register itself
does not occupy any addressable memory location. The
register is composed of latches that store the commands,
along with the address and data information needed to
