TLC372中文资料双路通用 LinCMOS™ 差分比较器数据手册TI规格书

描述 Description

This device is fabricated using LinCMOS™ technology and consists of two independent voltage comparators, each designed to operate from a single power supply. Operation from dual supplies is also possible if the difference between the two supplies is 2 V to 18 V. Each device features extremely high input impedance (typically greater than 1012Ω), allowing direct interfacing with high-impedance sources. The outputs are n-channel open-drain configurations and can be connected to achieve positive-logic wired-AND relationships.

The TLC372 has internal electrostatic discharge (ESD) protection circuits and has been classified with a 1000-V ESD rating using human body model testing. However, care should be exercised in handling this device as exposure to ESD may result in a degradation of the device parametric performance.

The TLC372C is characterized for operation from 0°C to 70°C. The TLC372I is characterized for operation from –40°C to 85°C. The TLC372M is characterized for operation over the full military temperature range of –55°C to 125°C. The TLC372Q is characterized for operation from –40°C to 125°C.

简介

TLC372属于集成电路（IC）的比较器。由TI制造生产的TLC372比较器逻辑比较器系列产品用于根据以数字格式表示的信息比较结果来生成输出；身份型比较器指示两个输入是否相同，幅度型比较器还指示两个输入不相同时哪个较大。它们不同于比较两个模拟输入幅度的器件，后者称为线性比较器且单独分类。
