Overview

モノリシック・タイマ回路 MC1455 は、非常に安定したコントローラで、正確な時間遅延や発振を生成できます。必要に応じてトリガやリセットの端子を追加できます。時間遅延モードでは、1 つの外部抵抗器/キャパシタによって、時間が正確に制御されます。発振器として安定動作をすることで、自走周波数とデューティ比のいずれも、外部抵抗器 2 つとキャパシタ 1 つで正確に制御されます。回路は立ち下がり波形でトリガ/リセットされ、出力構造によって最大 200 mA をソース／シンクしたり TTL 回路を駆動したりできます。

  • Direct Replacement for NE555 Timers
  • Timing from Microseconds through Hours
  • Operates in Both Astable and Monostable Modes
  • Adjustable Duty Cycle
  • High Current Output Can Source or Sink 200 mA
  • Output Can Drive TTL
  • Temperature Stability of 0.005% per °C
  • Normally ON or Normally OFF Output
  • Pb-Free Packages are Available

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.)
