3 說明
TXU0204 是一款 4 位雙電源同相定向電壓電平轉(zhuǎn)換器件。Ax 引腳以 VCCA 邏輯電平為基準(zhǔn)，OE 引腳可以 VCCA 或 VCCB 邏輯電平為基準(zhǔn)，Bx 引腳以 VCCB 邏輯電平為基準(zhǔn)。A 端口能夠接受 1.1V 至 5.5V 的輸入電壓，而 B 端口也可接受 1.1V 至 5.5V 的輸入電壓。如果 OE 相對(duì)于任一電源設(shè)為高電平，可能會(huì)發(fā)生從 A 到 B 或從 B 到 A 的定向數(shù)據(jù)傳輸。OE 設(shè)為低電平時(shí)，所有輸出引腳均處于高阻抗?fàn)顟B(tài)。請(qǐng)參閱器件功能模式，簡(jiǎn)要了解控制邏輯運(yùn)行。
