概览

MC74VHCT573A 是一款先进的高速 CMOS 八路锁存，带 3 态输出，采用硅门极 CMOS 工艺制造。它实现了与同等双极肖特基 TTL 相似的高运行速度，同时保持了 CMOS 低功耗。此 8 位 D 型锁存由锁存启用和输出启用输入控制。当输出启用输入为高电平时，八个输出会处于高阻抗状态。VHCT 输入可与 TTL 电平兼容。此器件可用作电平转换器，用于接口 3.3V 和 5.0V，因为它具有全 5V CMOS 电平输出摆幅。VHCT573A 输入和输出（禁用时）结构在应用 0 - 5.5V 的电压时提供保护，而无论电源电压如何。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。

  • High Speed: tPD = 7.7ns (Typ) at VCC = 5V
  • Low Power Dissipation: ICC = 4µA (Max) at TA = 25 C
  • TTL-Compatible Inputs: VIL = 0.8V; VIH = 2.0V
  • Power Down Protection Provided on Inputs and Outputs
  • Balanced Propagation Delays
  • Designed for 4.5V to 5.5V Operating Range
  • Low Noise: VOLP = 1.6V (Max)
  • Pin and Function Compatible with Other Standard Logic Families
  • Latchup Performance Exceeds 300mA
  • ESD Performance: HBM > 2000V; Machine Model > 200V
  • Chip Complexity: 234 FETs or 58.5 Equivalent Gates
  • Pb-Free Packages are Available*
