概览

MM74HC273 边触发触发器利用先进的硅门极 CMOS 工艺来实施 D 型触发器。它们与低功耗肖特基 TTL 电路相比，具有高抗扰性、低功耗和更高速度。此器件包含 8 个主-从触发器，带公共时钟和公共清除。D 输入上符合设置和保持时间要求的数据在时钟输入的低-高电平转换时传输至 Q 输出。清除输入为低电平时会将所有输出设置为低电平状态。每个输出均可驱动相当于 10 个低功耗肖特基 TTL 的负载。MM74HC273 可与 74LS273 实现功能兼容。通过对二极管联接 VCC 和接地，防止所有输入因静电放电受损。

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

  • 典型传播延迟： 18 ns
  • 宽工作电压范围
  • 低输入电流： 1µA，最大值
  • 低静态电流： 80 µA（74系列）
  • 输出驱动： 10 LS-TTL负载

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.)
