Introduction

This section contains electrical characteristics of the device as well as temperature and

power considerations.

This product contains devices to protect the inputs against damage due to high static

voltages. However, it is advisable to take precautions to avoid applying any voltage higher

than the specified maximum rated voltages.

To enhance reliability, unused inputs can be driven to an appropriate logic voltage level (VDD

or VSS). This could be done by the internal pull-up and pull-down, which is provided by the

product for most general purpose pins.

The parameters listed in the following tables represent the characteristics of the device and

its demands on the system.

In the tables where the device logic provides signals with their respective timing

characteristics, the symbol “CC” for Controller Characteristics is included in the Symbol

column.
