概览

VHC240 是一款先进的高速 CMOS 八路总线缓冲器，采用硅门极 CMOS 工艺制造。它能实现与同等双极肖特基 TTL 相似的高速运行，同时还保持 CMOS 低功耗。VHC240 是一款反相 3 态缓冲器，具有两个有效低电平输出启用。此器件适用于驱动总线或缓冲内存地址寄存器。输入保护电路可确保对输入引脚应用 0V 到 7V 电压而无需考虑电源电压。此器件可用作 5V 系统与 3V 系统以及两种电源系统的接口，如备用电池。此电路可防止器件由于不匹配的供电和输入电压而损坏。

  • This product is general usage and suitable for many different applications.
  • 高速： TA = 25°C时，tPD = 3.6 ns（典型值）
  • 低功耗： TA = 25°C时，ICC = 2 µA（最大值）
  • 高抗噪能力： VNIH = VNIL = 28% VCC （最小值）
  • 所有输入上都提供掉电保护
  • 低噪声： VOLP = 0.9V（最大值）
  • 引脚和功能与74HC240兼容
