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,

-

0.5V. During voltage transitions, A9,

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.
