74LVCH32244A是高性能、低功耗、低电压的硅栅CMOS器件,优于最先进的CMOS兼容TTL系列。输入可通过3.3 V或5.0 V器件进行驱动。在3态操作中,输出能够处理5 V的电压。这些特性允许在混合3.3 V和5 V环境中将这些器件用作转换器件。
74LVCH32244A是带3态输出的32位非反相缓冲器/线路驱动器。3态输出通过八个输出使能输入(1OE至 8OE)控制。针脚nOE上的高电平使输出呈高阻抗关断状态。
为确保上电或掉电期间的高阻抗状态,针脚nOE应当通过上拉电阻连接到VCC;最低电阻值由驱动器灌入电流的能力确定。
数据输入上的总线保持无需使用外部上拉电阻来将未使用的输入或浮动数据输入保持在有效的逻辑电平。
