OCTAL バス・トランシーバ

Active

Overview

MC74LVX245 は、高度な高速 CMOS OCTAL バス・トランシーバです。データ・バス間の双方向の非同期通信を目的としています。データ伝送の方向は、T/R 入力のレベルによって決まります。出力イネーブル・ピン (OE) を使用してデバイスを無効にできるため、バスが効果的に分離されます。すべての入力には、静電気放電に対する保護回路が装備されています。

  • High Speed: tPD = 4.7ns (Typ) at VCC = 3.3V
  • Low Power Dissipation: ICC = 4µA (Max) at TA = 25 C
  • Power Down Protection Provided on Inputs
  • Balanced Propagation Delays
  • 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 APPLICATION NOTES 1. Do not force a signal on an I/O pin when it is an active output, damage may occur. 2. All floating (high impedence) input or I/O pins must be fixed by means of pull up or pull down r
  • Pb-Free Packages are Available*
