CAHCT240IPWRG4Q1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

CAHCT240IPWRG4Q1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CAHCT240IPWRG4Q1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/ordering information

This octal buffer/driver is designed specifically to

improve the performance and density of 3-state

memory-address drivers, clock drivers, and

bus-oriented receivers and transmitters.

The SN74AHCT240 device is organized as two 4-bit

buffers/line drivers with separate output-enable (OE)

inputs. When OE is low, the device passes data from

the A inputs to the Y outputs. When OE is high, the

outputs are in the high-impedance state.

To ensure the high-impedance state during power up or power down, OE shall be tied to VCC through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
