TLV2354IDR集成电路（IC）的比较器规格书PDF中文资料

TLV2354IDR属于集成电路（IC）的比较器。由德州仪器制造生产的TLV2354IDR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。

description

The TLV2354 consists of four independent,

low-power comparators specifically designed for

single power-supply applications and operateS

with power-supply rails as low as 2 V. When

powered from a 3-V supply, the typical supply

current is only 240 mA.

The TLV2354 is designed using the Texas Instruments LinCMOSE technology and, therefore, features an

extremely high input impedance (typically greater than 1012 W), which allows direct interfacing with

high-impedance sources. The outputs are N-channel open-drain configurations that require an external pullup

resistor to provide a positive output voltage swing, and they can be connected to achieve positive-logic

wired-AND relationships. The TLV2354I is fully characterized for operation from – 40°C to 85°C. The TLV2354M

is fully characterized for operation from – 55°C to 125°C.

The TLV2354 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.
