The MC14049UB hex inverter/buffer is constructed with MOS P?channel and N?channel enhancement mode devices in a single monolithic structure. This complementary MOS device finds primary use where low power dissipation and/or high noise immunity is desired. This device provides logic?level conversion using only one supply voltage, VDD. The input?signal high level (VIH) can exceed the VDD supply voltage for logic?level conversions. Two TTL/DTL Loads can be driven when the device is used as CMOS?to?TTL/DTL converters (VDD = 5.0 V, VOL
0.4 V, IOL ≥ 3.2 mA). Note that pins 13 and 16 are not connected internally on this device; consequently connections to these terminals will not affect circuit operation.

MC14049UBDTR2屬于集成電路（IC） > 門和反相器。安森美半導(dǎo)體公司制造生產(chǎn)的MC14049UBDTR2門和反相器邏輯柵極和逆變器系列中的產(chǎn)品對單個邏輯信號執(zhí)行基本邏輯運算（例如 AND、NOT、OR 等）。與觸發(fā)器不同，它們不能夠存儲信息，不會對提供給其輸入的信號立即做出響應(yīng)。雖然早就被集成電路實施形式所取代，以用于實現(xiàn)復(fù)雜功能，但分立柵極仍可在僅需要非常簡單邏輯功能的情況下使用。
