概览

74LVX4245 是 24 引脚双电源八路转换收发器，适用于在 3V/5V 混合电源环境（例如使用 3.3V CPU 和 5V LCD 显示器的笔记本电脑）在 5V 总线和 3V 总线之间连接。A 端口连接 5V 总线；B 端口连接 3V 总线。发射/接收 (T/Rbar) 输入决定了数据流的方向。发射（有效高电平）使数据能够从 A 端口传送到 B 端口。接收（有效低电平）使数据能够从 B 端口传送到 A 端口。输出启用 (OEbar) 输入为高电平时，会将 A 端口和 B 端口置于 3 状态，从而将两者禁用。

  • Bi-directional Interface Between 5V and 3V Buses
  • Control Inputs Compatible with TTL Level
  • 5V Data Flow at A Port and 3V Data Flow at B Port
  • Outputs Source/Sink 24mA at 5V Bus and 12mA at 3V Bus
  • Guaranteed Simultaneous Switching Noise Level and Dynamic Threshold Performance
  • Available in SOIC and TSSOP Packages
  • Functionally Compatible with the 74 Series 245
  • 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.)
