描述

CD54HC4511，CD74HC4511和CD74HCT4511是BCD至7段鎖存器/解碼器/驅(qū)動(dòng)器，具有四個(gè)地址輸入（D ₀ ?? D ₃），有效低消隱（BL）\輸入，燈測試（LT）\輸入和鎖存使能（LE）\輸入，當(dāng)高電平時(shí)，使能用于存儲(chǔ)BCD輸入的鎖存器。當(dāng)LE \為低電平時(shí)，鎖存器被禁用，使輸出對(duì)BCD輸入透明。

這些器件具有標(biāo)準(zhǔn)尺寸的輸出晶體管，但能夠輸出（標(biāo)準(zhǔn)V _{OH < /sub>水平）4.5 V時(shí)最高7.5 mA.HC類型可在6 V時(shí)提供高達(dá)10 mA的電流。}
