SN74AHC16540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

SN74AHC16540属于集成电路（IC）的缓冲器驱动器接收器收发器。由德州仪器制造生产的SN74AHC16540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

These 16-bit buffers and bus drivers provide a

high-performance bus interface for wide data

paths.

The 3-state control gate is a 2-input AND gate with

active-low inputs so that if either output-enable

(OE1 or OE2) input is high, all corresponding

outputs are in the high-impedance state.

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

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

The SN54AHC16540 is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74AHC16540 is characterized for operation from –40°C to 85°C.
