概览

MM74HCT245 3 态双向缓冲器采用先进的硅门极 CMOS 工艺，适用于数据总线之间的双向异步通信。它具有高驱动电流输出，即使在驱动大总线电容时也能实现高速运行。此电路具有 CMOS 电路的低功耗，但与低功耗肖特基 TTL 电路相比仍然具有高速度。此器件具有 TTL 兼容输入，可驱动多达 15 个 LS-TTL 负载，所有输入均可通过联接 VCC 和接地的二极管进行静电放电防护。MM74HCT245 具有一个有效低电平启用输入 (G#)，和方向控制 (DIR)。当 DIR 输入为高电平时，数据从 A 输入流动到 B 输出。当 DIR 为低电平时，数据从 B 流向 A。MM74HCT 器件适用于 TTL 和 NMOS 组件与标准 CMOS 器件之间的接口。此类零件也是 LS-TTL 器件的插件替代品，可用于降低现有设计的功耗。

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.)
