低逻辑电平
Logic Level - Low | The SN74AHC2G157H is 2-line to 1-line data selecter/multiplexer designed for 2.0V to 5.5V Vcc operation, The SN74AHC2G157H feature a common strobe(G)input.When the strobe is high,all outputs are low.When the strobe is low,a 1-bit word is selected from one of two sources and is routed to the outputs.The devices present true data. The SN74AHC2G157H is characterized for operation from -40℃ to 85℃. Operating Range 2V to 5.5V Vcc Switching Speed 6.2ns Low power Dissipation Icc 2μA All inputs VIH=5.5V 8pin DCT Package |
高逻辑电平
Logic Level - High | SN74AHC2G157H是2线1线数据选择器/多路复用器，专为2.0V至5.5V的VCC操作。SN74AHC2G157H设有一个共同的选通信号（G）输入。当选通信号高，所有输出低。当选通信号为低电平时，从两个来源之一选择一个1位字，被路由到输出。该设备呈现真正的数据。SN74AHC2G157H的特点是操作从-40℃至85℃。 工作范围2V至5.5V的VCC 开关速度6.2ns 低功率耗散ICC2μA 所有输入VIH=5.5V 8引脚DCT封装 |
