概览

MC74AC646/74ACT646 由带输出的寄存总线收发器电路、 D 型触发器和控制电路组成，提供从输入总线或内部存储寄存器的多路复用数据传输。 A 或 B 总线上的数据将在相应时钟引脚（CAB 或 CBA）的低-高电平转换时加载到相应的寄存器中。 提供的四个基本数据处理功能 如下图所示。

  • Independent Registers for A and B Buses
  • Multiplexed Real-Time and Stored Data Transfers
  • Choice of True and Inverting Data Paths
  • 3-State Outputs
  • 300 mil Slim Dual In-Line Package
  • Outputs Source/Sink 24 mA
  • ACT646 Has TTL Compatible Inputs
  • These devices are available in Pb-free package(s). Specifications herein apply to both standard and Pb-free devices. Please see our website at www.onsemi.com for specific Pb-free orderable part numbers, or contact your local ON Semiconductor sales office or representative.

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.)
