概览

MC74LCX541 是一款高性能双非逆变缓冲器，运行电压为 2.3 V 到 3.6V。此器件的功能与 MC74LCX244 相似，后者提供通流结构。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 MC74LCX541 输入能够基于 5V 器件进行安全驱动。MC74LCX541 适用于内存地址驱动和所有 TTL 级总线导向收发器应用。输出处的电流驱动能力为 24mA。输出启用（OE1bar，OE2bar）输入如果为高电平则会将输出置于高电平 Z 状态，从而将其禁用。

  • 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 (10mA)
    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.)
