| 电源电压VccVoltage - Supply | |
| 静态电流IqCurrent - Quiescent (Max) | 单电源 Single Supply |
| 输出高，低电平电流Current - Output High, Low | 2.0 V ~ 5.5 V |
| 低逻辑电平Logic Level - Low | The HD74LVC139 has two independent two-to-four-line decoders each with a single active low enable input in a 16 pin package. Data on the select inputs cause one of the four normally high outputs to go low. Low voltage and highspeed operation is suitable at the battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation. VCC = 2.0 V to 5.5 V All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C) High output current ±24 mA (@VCC = 3.0 V to 5.5 V) Ordering Information |
| 高逻辑电平Logic Level - High | HD74LVC139在16引脚封装中有两个独立的两到四线解码器，且每个有着单一的低电平有效使能输入。选择输入端的数据会导致四个常高的输出端的其中一个变低。低电压和高速操作，适合于电池驱动的产品（笔记本式个人计算机）和低功耗能够延长电池的寿命用于很长一段时间的操作。 VCC=2.0 V至5.5 V 所有输入VIH（最大）=5.5 V（VCC= 0 V至5.5 V） 典型的VOL接地反弹<0.8 V（@ VCC=3.3 V，Ta=25°C） 典型的VOH下冲>2.0 V（VCC= 3.3 V，Ta= 25°C） 高输出电流±24毫安（@ VCC=3.0 V至5.5 V） 订购信息 |
