概览

74VCX16373 是一款性能先进的非反相 16 位透明锁存。该锁存适用于1.8V、2.5V 或 3.3V 系统中的超高速、超低功耗运行。VCX16373 为字节控制，每个字节功能相同，但又各自独立。每个字节有单独的输出启用和锁存启用输入。这些控制引脚可连在一起，以获得完整的 16 位操作。在 2.5 V（或 1.8 V）电压下运行时，该部件可耐受其与 3.3 V 总线连接时输入或输出可能遇到的电压。它确保可容限过电压 3.6 V。74VCX16373 包含带 3 态 3.6V 耐受输出的 16 D 型锁存。当锁存启用 (LEn) 输入为高电平时，Dn 输入上的数据进入锁存。在这种情况下，锁存为透明（每次其 D 输入更改时，锁存输出都会改变状态）。当 LE 为低电平时，锁存储存 LE 从高电平至 低电平转换之前的设置时间内 D 输入中出现的信息。3 态输出由输出启用 (OEn) bar 输入控制。当 OEbar 为低电平时，启用输出。当 OEbar 为高电平时，标准输出处于高阻抗状态，但这不会干扰进入锁存的新数据。
