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

簡介

LM319屬于集成電路（IC）的比較器。由制造生產的LM319比較器邏輯比較器系列產品用于根據以數字格式表示的信息比較結果來生成輸出；身份型比較器指示兩個輸入是否相同，幅度型比較器還指示兩個輸入不相同時哪個較大。它們不同于比較兩個模擬輸入幅度的器件，后者稱為線性比較器且單獨分類。
