Notes:
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 +0.5V. During voltage transitions,
input or I/O pins may overshoot to VCC +2.0V for periods
up to 20ns.
2. Minimum DC input voltage on A9, OE and RESET is -
0.5V. During voltage transitions, A9, OE and RESET may
overshoot 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.
*Comments
Stresses above those listed under "Absolute Maximum
Ratings" may cause permanent damage to this device. 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.

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 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.
