概览

VHCT244A 是一种先进的高速 CMOS 八路总线收发器，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，同时还能保持 CMOS 低功耗。VHCT244A 是一款非反向 3 态缓冲器，具有两个有效低电平输出启用。该器件可用作 3 态内存地址驱动器、时钟驱动器和总线导向的发射器/接收器。保护电路可确保对输入和输出（注释 1）引脚应用 0V 到 7V 电压而无需考虑电源电压。这些电路可防止器件由于不匹配的供电和输入/输出电压而损坏。此器件可用于将 5V 系统与 3V 系统以及两种电源系统的接口，如备用电池。

  • This product is general usage and suitable for many different applications.

  • 高速： VCC = 5V时，tPD = 5.9 ns（典型值）
  • 所有输入上都提供掉电保护
  • 低功耗： TA = 25°C时，ICC = 2 µA（最大值）
  • 引脚和功能与74HCT244兼容

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
