74LVC16240A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

74LVC16240A属于集成电路（IC）的缓冲器驱动器接收器收发器。由安世半导体(中国)有限公司制造生产的74LVC16240A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。

1. General description

The 74LVC16240A is a 16-bit inverting buffer/line driver with 3-state outputs. The device can be

used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. The device features four output

enables (1OE, 2OE, 3OE and 4OE), each controlling four of the 3-state outputs. A HIGH on nOE

causes the outputs to assume a high-impedance OFF-state.

Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be applied to

the outputs. These features allow the use of these devices in mixed 3.3 V and 5 V applications.

This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry

disables the output, preventing the damaging backflow current through the device when it is

powered down.
