Notes:
1. Minimum DC voltage on input or I/O pins is -0.5V. During
voltage transitions, inputs may undershoot VSS to -2.0V
for periods of up to 20ns. Maximum DC voltage on output
and I/O pins is VCC +0.5V. During voltage transitions,
outputs may overshoot to VCC +2.0V for periods up to
20ns.
2. Minimum DC input voltage on A9 pins is -0.5V. During
voltage transitions, A9 and
OE
may overshoot VSS to -
2.0V for periods of up to 20ns. Maximum DC input
voltage on A9 and
OE
is +12.5V which may overshoot to
13.5V 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.
