LM393LV集成電路（IC）的比較器規(guī)格書(shū)PDF中文資料

LM393LV屬于集成電路（IC）的比較器。由德州儀器制造生產(chǎn)的LM393LV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(lái)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(chēng)為線(xiàn)性比較器且單獨(dú)分類(lèi)。

3 Description

The LV device family consists of single, dual and quad

independent voltage comparators that operate from

a wide supply voltage range. The LV devices can

drop-in replace the standard TL331, LM2xx, LM3xx

and LM290x comparator family in low voltage (≤ 5

V) applications for improved performance and added

features.

The LV devices include a Power-On-Reset (POR)

feature to ensures the output is in a High-Z state

until the minimum supply voltage has been reached to

prevent output transients during power-up and powerdown.

The family also feature Rail to Rail inputs that

can go up to 6V without damage or phase inversion.

The LV devices are specified for the temperature

range of -40°C to +125°C, which covers the ranges

of the TL331, LM2xx, LM3xx and LM290x comparator

families.
