概览

VHC595 是一种先进的高速 CMOS 移位寄存器多谐振荡器，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。该器件包含一个 8 位串行输入并行输出移位寄存器，馈送 8 位 D 型存储寄存器。该存储寄存器具有八个 3 态输出。为移位寄存器和存储寄存器均提供单独的时钟。移位寄存器具有一个直接超控的清除串行输入，以及用于级联的多个串行输出（标准）引脚。移位寄存器和存储寄存器均使用正边触发时钟。如果两个时钟互相联接，移位寄存器状态则总是比存储寄存器提前一个时钟脉冲。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。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： VCC = 5V时，tPD = 5.4 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（典型值）
  • 引脚和功能与74HC595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.)
