Understanding and Interpreting
Standard-Logic Data Sheets
Stephen M.Nolan, Jose M. Soltero, Shreyas Rao
ABSTRACT
Texas Instruments (TI) standard-logic product data sheets include descriptions of functionality and
electrical specifications for the devices. Each specification includes acronyms, numerical limits, and test
conditions that may be foreign to the user. The proper understanding and interpretation of the direct, and
sometimes implied, meanings of these specifications are essential to correct product selection and
associated circuit design. This application report explains each data sheet parameter in detail, how it
affects the device, and how it impacts the application. This will enable component and system-design
engineers to derive the maximum benefit from TI logic devices.

Introduction
This application report is a synopsis of the information available from a typical TI data sheet with the
purpose of assisting component and system-design engineers in selecting Texas Instruments (TI)
standard-logic products. Information includes a brief description of terms, definitions, and testing
procedures currently used for commercial, automotive and military specifications. Symbols, terms, and
definitions generally are in accordance with those currently agreed upon by the JEDEC Solid State
Technology Association for use in the USA and by the International Electrotechnical Commission (IEC) for
international use.
