TLV7044QPWRQ1集成电路（IC）的比较器规格书PDF中文资料

TLV7044QPWRQ1属于集成电路（IC）的比较器。由德州仪器制造生产的TLV7044QPWRQ1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。

3 Description

The TLV703x-Q1/TLV704x-Q1 are low-voltage,

nanopower comparators with rail-to-rail inputs. These

comparators are applicable for space-critical and

power conscious designs like infotainment, telematics,

and head unit applications.

The TLV703x-Q1 and TLV704x-Q1 offer an excellent

combination of power and speed. The benefit of

fast response time at nanopower enables powerconscious

systems to monitor and respond quickly to

fault conditions. With an operating voltage range of

1.6 V to 6.5 V, these comparators are compatible with

1.8 V, 3 V, and 5 V systems.

The TLV703x-Q1 and TLV704x-Q1 also ensure no

output phase inversion with overdriven inputs and

internal hysteresis, so engineers can use this family of

comparators for precision voltage monitoring in harsh,

noisy environments where slow-moving input signals

must be converted into clean digital outputs.

The TLV703x-Q1 have a push-pull output stage

capable of sinking and sourcing milliamps of current.

The TLV704x-Q1 have an open-drain output stage

that can be pulled beyond VCC.
