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.

LM393LVDDFR属于集成电路（IC） > 比较器。美国德州仪器公司制造生产的LM393LVDDFR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。
