德克萨斯仪器（TI）标准逻辑产品数据表包括设备的功能和电气规格说明。每个规范包括缩写，数值限制和测试条件，可能是外国的用户。正确理解和解释这些规格的直接的，有时是隐含的，意义是正确的产品选择和相关电路设计的关键。此应用程序报告详细解释每个数据表参数，它如何影响设备，以及它如何影响应用程序。这将使组件和系统设计工程师从TI的逻辑器件获得最大的利益。(Texas Instruments (TI) standard-logic product data sheets include descr iptions 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.)
