Overview

MC74VHC125 は高速 CMOS クワッド・バス・バッファであり、シリコン・ゲート CMOS テクノロジで製造されています。CMOS の低電力消費を維持したまま、同等のバイポーラ・ショットキー TTL と同じ高速動作を実現します。MC74VHC125 では 3 ステート制御入力 (OEbar) を High に設定して出力を高インピーダンス状態にする必要があります。内部回路は、高ノイズ耐量と安定出力を実現するバッファ出力を含む、3 つの段から成ります。入力は最大 7V までの電圧に耐え、5V システムから 3V システムへのインタフェースが可能です。

  • High Speed: tPD = 3.8ns (Typ) at VCC = 5V
  • Low Power Dissipation: ICC = 4mA (Max) at TA = 25°C
  • High Noise Immunity: VNIH = VNIL = 28% VCC
  • Power Down Protection Provided on Inputs
  • Balanced Propagation Delays
  • Designed for 2V to 5.5V Operating Range
  • Low Noise: VOLP = 0.8V (Max)
  • Pin and Function Compatible with Other Standard Logic Families
  • Latchup Performance Exceeds 300mA
  • ESD Performance: HBM > 2000V; Machine Model > 200V
  • Chip Complexity: 72 FETs or 18 Equivalent Gates
  • 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.)
