Overview

MC74AC646/74ACT646 は、登録バス・トランシーバ回路で構成されており、出力、D タイプ・フリップフロップ、および入力バスまたは内部ストレージ・レジスタから直接データを多重送信する制御回路を備えています。 A または B バス上のデータは、適切なクロックピン (CAB または CBA) の LOW から HIGH への遷移でそれぞれのレジスタにロードされます。 次の図に、利用可能な 4 つの基本的なデータ処理機能を示します。

  • 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.)
