Overview

MC14521B は、3 つの動作モードを可能にする入力回路を備えた 24 個のフリップフロップのチェーンで構成されています。入力は、水晶発振器、RC 発振器、または外部発振器の入力バッファとして機能します。各フリップフロップは前のフリップフロップの周波数を 2 で割るので、この部分は 224 = 16,777,216 までカウントされます。カウントは、クロックの負方向エッジで進みます。最後の 7 段の出力は、柔軟性を高めるために使用できます。

  • All Stages are Resettable
  • Reset Disables the RC Oscillator for Low Standby Power Drain
  • RC and Crystal Oscillator Outputs Are Capable of Driving External Loads
  • Test Mode to Reduce Test Time
  • VDD' and VSS' Pins Brought Out on Crystal Oscillator Inverter to Allow the Connection of External Resistors for Low-Power Operation
  • Supply Voltage Range = 3.0 Vdc to 18 Vdc
  • Capable of Driving Two Low-power TTL Loads or One Low-power Schottky TTL Load over the Rated Temperature Range.
  • 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.)
