概览

MC74LCX16244 是一款高性能双非反相 16 位缓冲器，运行电压为 2.3 到 3.6V。该器件为半字节控制。每个半字节均具有单独的输出启用输入，可进行联结以实现完全 16 位运行。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 MC74LCX16244 输入能够基于 5V 器件进行安全驱动。MC74LCX16244 适用于内存地址驱动和所有 TTL 级总线导向收发器应用。最大 4.5ns 的传播延迟支持高性能应用。电流驱动能力为输出处 24mA。输出启用输入 (OEn)bar 如果为高电平则会将它们置于高电平 Z 状态，从而将两者禁用。MC74LCX16244 包含十六个带 3 态 5V 耐压输出的非反相缓冲器。该器件为半字节控制，每个半字节功能完全相同，但独立运行。控制引脚可以联接在一起以实现完全 16 位运行。3 态输出由每个半字节的输出启用 (OEn)bar 输入控制。当 OEnbar 为低电平时，输出导通。当 OEnbar 为高电平时，输出为高阻抗状态。

  • Designed for 2.3 to 3.6V VCC Operation

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.)
