概览

高性能硅门极 CMOS MC74HC157A 与 LS157 的引脚输出相同。该器件输入与标准 CMOS 输出兼容；带有上拉电阻，它们与 LSTTL 输出兼容。 此器件将 2 个半字节（A 或 B）发送到一个由选择输入决定的端口 (Y)。数据以非倒转形式在输出端呈现。输出启用输入上的高电平会将四个 Y 输出全部设为低电平。

  • Output Drive Capability: 10 LSTTL Loads
  • Outputs Directly Interface to CMOS, NMOS, and TTL
  • Operating Voltage Range: 2.0 to 6.0 V
  • Low Input Current: 1.0 mA
  • High Noise Immunity Characteristic of CMOS Devices
  • In Compliance with the Requirements Defined by JEDEC Standard No. 7A
  • Chip Complexity: 82 FETs or 20.5 Equivalent Gates
  • Pb-Free Packages are Available*
