HD74LV21ATELL中文资料瑞萨数据手册PDF规格书

描述 Description

The HD74LV21A performs the Boolean functions Y = A•B•C•D or Y = A+B+C+D in positive logic. Low-voltage and high-speed operation is suitable for the battery-powered products (e.g., notebook computers), and the low-power consumption extends the battery life.

特性 Features
