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.

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.
