A29800 Series
Absolute Maximum Ratings*
*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.

Notes:
Commercial (C) Devices
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.

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.
