SN74LVC126ADBR集成電路（IC）的緩沖器驅(qū)動(dòng)器接收器收發(fā)器規(guī)格書PDF中文資料

SN74LVC126ADBR屬于集成電路（IC）的緩沖器驅(qū)動(dòng)器接收器收發(fā)器。由德州儀器制造生產(chǎn)的SN74LVC126ADBR緩沖器，驅(qū)動(dòng)器，接收器，收發(fā)器邏輯緩沖器、驅(qū)動(dòng)器、接收器和收發(fā)器允許隔離對(duì)某個(gè)電路的邏輯信號(hào)的訪問(wèn)，以用于另一電路。緩沖器將其輸入信號(hào)（不變或反相）傳遞到其輸出，并可能用于清除弱信號(hào)或驅(qū)動(dòng)負(fù)載。在布爾邏輯仿真器中，緩沖器主要用于增加傳播延遲。邏輯接收器和收發(fā)器允許在數(shù)據(jù)總線之間進(jìn)行隔離通信。

3 Description

The SN74LVC126A device is a quadruple bus buffer

gate designed for 1.65V to 3.6V VCC operation.

The SN74LVC126A device features independent line

drivers with 3-state outputs. Each output is disabled

when the associated output-enable (OE) input is low.

To ensure the high-impedance state during power up

or power down, OE must be tied to GND through a

pulldown resistor; the minimum value of the resistor

is determined by the current-sourcing capability of the

driver.

Inputs can be driven from either 3.3V or 5V

devices. This feature allows the use of this device

as a translator in a mixed 3.3V and 5V system

environment.
