製品

Overview

MC74VHC244は高度な高速CMOS8進バス・バッファであり、シリコン・ゲートCMOSテクノロジーで製造されています。MC74VHC244は非反転3ステート・バッファであり、2つのアクティブLOW出力が有効化されています。3ステート・メモリ・アドレス・ドライバなどで使用されるよう設計されています。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。入力耐性は最大7V、5Vシステムから3Vシステムへのインターフェースが可能です。

  • High Speed: tPD = 3.9ns (Typ) at VCC = 5V
  • Low Power Dissipation: ICC = 4µA (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 = 0.9V (Max)
  • Pin and Function Compatible with Other Standard Logic Families
  • Latchup Performance Exceeds 300mA
  • ESD Performance: HBM > 2000V; Machine Model > 200V
  • Chip Complexity: 136 FETs
  • 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.)
