Datasheet

製品

Overview

MC74LCX244 は、2.3 ～ 3.6V 電源で動作する高性能非反転 OCTAL バッファです。高インピーダンス TTL 対応入力は入力ドライバに負荷がかかる電流を著しく低減し、TTL 対応出力はスイッチングノイズ性能を向上させます。5.5V の VI 仕様により MC74LCX244 入力を 5V デバイスで安全に駆動することができます。MC74LCX244 はメモリ・アドレスの駆動やあらゆる TTL レベル・バス指向トランシーバのアプリケーションに適しています。電流駆動能力は出力で 24 mA です。出力イネーブル (OEbar) 入力が HIGH になると、出力は HIGH Z 状態になって無効になります。

  • Desktop

  • Designed for 2.3 to 3.6V VCC Operation
  • 5V Tolerant - Interface Capability With 5V TTL Logic
  • Supports Live Insertion and Withdrawal
  • IOFF Specification Guarantees High Impedance When VCC = 0V
  • LVTTL Compatible
  • LVCMOS Compatible
  • 24mA Balanced Output Sink and Source Capability
  • Near Zero Static Supply Current in All Three Logic States (10µA) Substantially Reduces System Power Requirements
  • Latchup Performance Exceeds 500mA
  • ESD Performance: Human Body Model >2000V; Machine Model >200V
  • 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.)
