双 64 位静态移位寄存器

Active

概览

MC14517B 双 64 位静态移位寄存器由两个相同的独立 64 位寄存器组成。每个寄存器在 16、32、48 和 64 处具有单独的时钟和写入启用输入。数据输入处的数据通过时钟输入,而无论写入启用输入的状态如何。当写入启用输入为高电平时,输出将禁用(开路)。在此期间,显示在数据输入以及 16 位、32 位、48 位点触的数据可通过应用时钟脉冲输入到该器件中。此功能使得寄存器能够以 16 时钟时段加载 64 位,还允许使用总线逻辑。此器件用于时间延迟电路、临时存储器存储电路和其他串行移位寄存器应用。

  • Diode Protection on All Inputs
  • Fully Static Operation
  • Output Transitions Occur on the Rising Edge of the Clock Pulse
  • Exceedingly Slow Input Transition Rates May Be Applied to the Clock Input
  • 3-State Output at 64th-Bit Allows Use in Bus Logic Applications
  • Shift Registers of any Length may be Fully Loaded with 16 Clock Pulses
  • Supply Voltage Range = 3.0 Vdc to 18 Vdc
  • Capable of Driving Two Low-power TTL Loads or One Low-power Schottky TTL Load Over the Rated Temperature Range
  • Pb-Free Packages are Available
