概览

LVT573和LVTH573包含八个带有3态输出的闩锁，适合用于总线结构的系统应用。 当锁存使能(LE)为高电平时，锁存器对于数据而言是透明的。 当LE为低电平时，满足输入时序要求的数据被锁存。 当输出使能(OE#)为低电平时，数据显示在总线上。 当OE#为高电平时，总线输出处于高阻抗状态。 LVTH573数据输入包含总线保持功能，无需外部上拉电阻即可保持未用的输入。 这些八通道闩锁设计用于低电压(3.3V) VCC应用，也可向5V环境提供TTL接口。 LVT573和LVTH573采用先进的BiCMOS技术制造，可实现类似于5V ABT的高速运行，同时又能维持较低的CMOS功耗。

  • This product is general usage and suitable for many different applications.
  • 系统在5V VCC时的输入和输出接口能力
  • 总线保持数据输入无需外部上拉电阻即可保持未用的输入(74LVTH573)，另外还提供不含总线保持功能的配置(74LVT573)。
  • 允许带电插/拔
  • 上电/掉电高阻抗提供无干扰总线负载
  • -32 mA/+64 mA输出源电流/灌电流
  • 功能上兼容74系列573
  • 闩锁性能超过500 mA
  • 静电放电(ESD)性能：人体模型> 2000V机械模型> 200V充电器件模型> 1000V
