CD74HCT244中文资料具有 TTL 兼容型 CMOS 输入和三态输出的 6 通道、4.5V 至 5.5V 缓冲器数据手册TI规格书

描述 Description

The ’HC240 and ’HCT240 are inverting three-state buffers having two active-low output enables. The CD74HC241, ’HCT241, ’HC244 and ’HCT244 are non-inverting three-state buffers that differ only in that the 241 has one active-high and one active-low output enable, and the 244 has two active-low output enables. All three types have identical pinouts.

简介

CD74HCT244属于集成电路（IC）的缓冲器驱动器接收器收发器。由TI制造生产的CD74HCT244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。
