低逻辑电平
Logic Level - Low | This single 2-line to 1-line data selector/multiplexer is designed for 1.65-V to 5.5-V VCC operation.The SN74LVC2G157 features a common strobe (G) input. When the strobe is high, Y is low and Y is high.When the strobe is low, a single bit is selected from one of two sources and is routed to the outputs. The device provides true and complementary data.NanoFree™ package technology is a major breakthrough in IC packaging concepts, using the die as the package.This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,preventing damaging current backflow through the device when it is powered down. Available in the Texas Instruments NanoFree™ Package Supports 5-V VCC Operation Inputs Accept Voltages to 5.5 V Max tpd of 6 ns at 3.3 V Low Power Consumption, 10-µA Max ICC ±24-mA Output Drive at 3.3 V Typical VOLP(Output Ground Bounce)<0.8 V at VCC= 3.3 V, TA= 25°C |
高逻辑电平
Logic Level - High | 这个单-2线1线数据选择器/多路复用器专为1.65-V到5.5 V的VCC操作。SN74LVC2G157拥有一个共同的选通信号（G）输入。当选通信号高，Y是低和Y是高。当选通信号为低电平时，一个位从两个源之一被选择和被路由到输出。该器件提供真正的和互补的数据。 NanoFreeTM包装技术是IC包装概念的重大突破。这个装置是完全指定的部分断电应用程序使用IOFF。当断电时，IOFF电路关闭输出，防止破坏回流电流通过设备。 NanoFree™包装 支持5-V VCC操作 接受输入电压到5.5 V 最大TPD为6 ns，在3.3 V时 低功耗，10μA最大ICC ±24 mA输出驱动，在3.3 V时 典型的VoIP（输出地弹跳）<0.8 V，在VCC=3.3 V，TA= 25°C时 |
