CD74HC4050PWR集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

CD74HC4050PWR属于集成电路（IC）的缓冲器驱动器接收器收发器。由美国德州仪器公司制造生产的CD74HC4050PWR缓冲器，驱动器，接收器，收发器逻辑缓冲器、驱动器、接收器和收发器允许隔离对某个电路的逻辑信号的访问，以用于另一电路。缓冲器将其输入信号（不变或反相）传递到其输出，并可能用于清除弱信号或驱动负载。在布尔逻辑仿真器中，缓冲器主要用于增加传播延迟。逻辑接收器和收发器允许在数据总线之间进行隔离通信。

Description

The ’HC4049 and ’HC4050 are fabricated with high-speed

silicon gate technology. They have a modified input

protection structure that enables these parts to be usedas

logic level translators which convert high-level logic to a lowlevel

logic while operating off the low-level logic supply. For

example, 15-V input pulse levels can be down-converted to

0-V to 5-V logic levels. The modified input protection

structure protects the input from negative electrostatic

discharge. These parts also can be used as simple buffers

or inverters without level translation. The ’HC4049 and

’HC4050 are enhanced versions of equivalent CMOS types.
