LM319集成电路（IC）的比较器规格书PDF中文资料

LM319属于集成电路（IC）的比较器。由意法半导体集团制造生产的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。

DESCRIPTION

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

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

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

They feature faster response than the LM111 at the expense of higher power dissipation. However, the high speed, wide operating voltage range and low package count make the much more versatile.

■ TWO INDEPENDENT COMPARATORS

■ OPERATES FROM A SINGLE +5V SUPPLY

■ TYPICALLY 80ns RESPONSE TIME AT ±15V

■ MINIMUM FAN-OUT OF 2 EACH SIDE

■ MAXIMUM INPUT CURRENT OF 1µA OVER OPERATING TEMPERATURE RANGE

■ INPUTS AND OUTPUTS CAN BE ISOLATED FROM SYSTEM GROUND

■ HIGH COMMON-MODE SLEW RATE
