TLC374中文资料四路通用 LinCMOS™ 差分比较器数据手册TI规格书

描述 Description

These quadruple differential comparators are fabricated using LinCMOSTM technology and consist of four independent voltage comparators 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 1012 ), 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 TLC374 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 degradation of the device parametric performance. The TLC374C is characterized for operation from 0°C to 70°C. The TLC374I is characterized for operation from -40°C to 85°C. The TLC374M is characterized for operation over full military temperature range of -55°C to 125°C. The TLC374Q is characterized for operation from -40°C to 125°C.

简介

TLC374属于集成电路（IC）的比较器。由TI制造生产的TLC374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。
