MC14049UB集成电路（IC）的门反相器规格书PDF中文资料

MC14049UB属于集成电路（IC）的门反相器。由安森美半导体公司制造生产的MC14049UB门和反相器逻辑栅极和逆变器系列中的产品对单个逻辑信号执行基本逻辑运算（例如 AND、NOT、OR 等）。与触发器不同，它们不能够存储信息，不会对提供给其输入的信号立即做出响应。虽然早就被集成电路实施形式所取代，以用于实现复杂功能，但分立栅极仍可在仅需要非常简单逻辑功能的情况下使用。

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.
