Overview

MC74AC139/74ACT139 は、高速、デュアル 1-of-4 デコーダ／デマルチプレクサです。このデバイスには 2 つの独立したデコーダがあり、それぞれが 2 つの入力を受け入れ、4 つの相互排他的なアクティブ LOW 出力を提供します。 各デコーダには、4 出力デマルチプレクサのデータ入力として使用できるアクティブ LOW イネーブル入力があります。 MC74AC139/74ACT139 の各半分は、2 つの変数の 4 つの最小項を提供する関数ジェネレータとして使用できます。

  • Multifunction Capability
  • Two Completely Independent 1-of-4 Decoders
  • Active LOW Mutually Exclusive Outputs
  • Outputs Source/Sink 24 mA
  • ACT139 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.)
