SN74LVC1G240DBVT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

SN74LVC1G240DBVT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SN74LVC1G240DBVT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

This single buffer/driver is designed for 1.65-V to 5.5-

V VCC operation.

The SN74LVC1G240 is a single line driver with a 3-

state output. The output is disabled when the output- enable (OE) input is high.

NanoFree™ package technology is a major

breakthrough in IC packaging concepts, using the die

as the package.

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.

This device is fully specified for partial-power-down

applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow

through the device when it is powered down.
