概览

MC74LCX245 是一款高性能非反向八路收发器，运行电压为 2.0 V 到 5.5V。高阻抗 TTL 兼容输入显著减少了输入驱动器的电流负载，而 TTL 兼容输出则提高了开关噪音性能。5.5V 的 VI 规格使得 MC74LCX245 输入能够基于 5V 器件进行安全驱动。MC74LCX245 适用于内存地址驱动和所有 TTL 级总线导向收发器应用。电流驱动能力在 A 和 B 端口均为 24mA。发射/接收 (T/Rbar) 输入决定了数据流经双向收发器的方向。发射（有效高电平）让数据能够从 A 端口流向 B 端口；接收（有效低电平）则让数据能够从 B 端口流向 A 端口。输出启用输入如果为高电平则会将 A 端口和 B 端口置于高电平 Z 状态，从而将两者禁用。

  • Designed for 2.0 to 5.5V 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 PIN
  • Pb-Free Packages

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.)
