SN74CBTLV1G125屬于集成電路（IC）的信號開關(guān)多路復用器解碼器。由美國德州儀器公司制造生產(chǎn)的SN74CBTLV1G125信號開關(guān)，多路復用器，解碼器邏輯型信號開關(guān)、多路復用器和編碼器 IC 可用于對以數(shù)字格式表示數(shù)據(jù)的電信號進行路由和選擇。這些器件與設(shè)計用于模擬信號的類似產(chǎn)品有所不同，它們保留的信息表示為兩個電狀態(tài)之一，而不是兩個外部界限內(nèi)的無窮變化量。

3 Description

The SN74CBTLV1G125 features a single high-speed

line switch. The switch is disabled when the outputenable

(OE) input is high.

This device is fully specified for partial-power-down

applications using Ioff. The Ioff feature ensures that

damaging current will not backflow through the device

when it is powered down. The device has isolation

during power off.

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.
