TLV2354IDR屬于集成電路（IC）的比較器。由美國德州儀器公司制造生產(chǎn)的TLV2354IDR比較器邏輯比較器系列產(chǎn)品用于根據(jù)以數(shù)字格式表示的信息比較結(jié)果來生成輸出；身份型比較器指示兩個(gè)輸入是否相同，幅度型比較器還指示兩個(gè)輸入不相同時(shí)哪個(gè)較大。它們不同于比較兩個(gè)模擬輸入幅度的器件，后者稱為線性比較器且單獨(dú)分類。

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.
