八路 3 态反相缓冲器/线路驱动器/线路接收器

Favorite

概览

高性能硅门极 CMOS MC74HC540A 与 LS540 的引脚输出相同。此器件输入与标准 CMOS 输出兼容。外部上拉电阻使其能够兼容 LSTTL 输出。 HC540A 是一款八路反相缓冲器/线路驱动器/线路接收器,适用于 3 态内存地址驱动器、时钟驱动器和其他总线导向系统。此器件的输入和输出在封装的对侧,且具有两个 AND 运算有效低电平输出启用。 HC540A 的功能与 HC541A 相似,具有非反相输出。

  • Output Drive Capability: 15 LSTTL Loads
  • Outputs Directly Interface to CMOS, NMOS and TTL
  • Operating Voltage Range: 2 to 6V
  • Low Input Current: 1mA
  • High Noise Immunity Characteristic of CMOS Devices
  • In Compliance With the JEDEC Standard No. 7A Requirements
  • Chip Complexity: 124 FETs or 31 Equivalent Gates
  • Pb-Free Packages are Available*
