概览
MC74VHC1GT126 是一款单门极非反向 3 态缓冲器，使用硅门极 CMOS 技术制造。它能实现与同等双极肖特基 TTL 相似的高速运行，同时还能保持 CMOS 低功耗。MC74VHC1GT126 需要 3 态控制输入 (OE(bar)) 设置为低电平才能将输出置于高阻抗状态。该器件输入可兼容 TTL 型输入阈值，输出则具有全 CMOS 电平输出摆幅。此器件上的输入保护电路允许输入上的耐过电压，使得此器件能够用作从 3.0V CMOS 逻辑到 5.0V CMOS 逻辑，或 1.8V CMOS 逻辑到 3.0V CMOS 逻辑的逻辑电平转换器，且能在高电压电源下运行。MC74VHC1GT126 输入结构在应用高达 5.5V 的电压时提供保护，而无论电源电压如何。因此使得 MC74VHC1GT126 可用作 5V 到 3V 电路的接口。输出结构还会在 VCC = 0V 时提供保护。这些输入和输出结构有助于防止电源电压 - 输入/输出电压不匹配、电池备用、热插入等导致的器件损坏。
