概览

LVXC4245 是一款 24 引脚双电源、8 位可配置电压接口收发器，适用于 PCMCIA 和其他实时可配置 I/O 应用。VCCA 引脚接受 5V 供应电平。A 端口是一个专用 5V 端口。VCCB 引脚接受 3V-5V 供应电平。B 端口配置为跟踪 VCCB 供应电平。VCC 引脚上的 5V 电平会在 5V 电平下配置 I/O 引脚，3V VCC 会在 3V 电平下配置 I/O 引脚。此器件将在 OE# 为高电平时允许 B 端口上的 VCCB 电源源引脚和 I/O 引脚浮动。要与 PCMCIA 插槽进行双向数据缓冲，以允许在正常运行期间插拔 PCMCIA 卡，必需此功能。

  • This product is general usage and suitable for many different applications.

  • 在5V和3V至5V总线之间可实现双向接口
  • 符合TTL电平要求的控制输入
  • 高达24 mA的输出源电流/灌电流
  • 保证同步开关噪声电平和动态阈值性能
  • 实施专利噪声/电磁干扰(EMI)消减电路
  • 广泛的VCCB工作电压范围：
  • 当OE#为高电平时，允许B端口和VCCB同时浮动
  • 功能上兼容74系列245

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.)
