LM319中文资料双高速比较器数据手册ST规格书

描述 Description

These products are precision high-speed dual comparators designed to operate over a wide range of supply voltages down to a single 5 V logic supply and ground. They feature low input currents and high gains.

The open collector of the output stage makes them compatible with transistor-transistor logic (TTL) as well as capable of driving lamps and relays at currents up to 25 mA.

Although designed primarily for applications requiring operation from digital logic supplies, these comparators are fully specified for power supplies up to ±15 V.

They feature faster response times than the LM111 at the expense of higher current consumption. However, the high speed, wide operating voltage range and low package count make the LM119, LM219, and LM319 much more versatile.

特性 Features

• Two independent comparators
• Supply voltage: +5 V to ±15 V
• Typically 80 ns response time at ±15 V
• Minimum fan-out of two each side
• Maximum input current of 1 μA over the operating temperature range
• Inputs and outputs can be isolated from system ground
• High common-mode slew rate

简介

LM319属于集成电路（IC）的比较器。由制造生产的LM319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。
