MC14094B数据手册集成电路（IC）的移位寄存器规格书PDF

描述 Description

The MC14094B combines an 8-stage shift register with a data latch for each stage and a three-state output from each latch. Data is shifted on the positive clock transition and is shifted from the seventh stage to two serial outputs. The QS output data is for use in high-speed cascaded systems. The Q S output data is shifted on the following negative clock transition for use in low-speed cascaded systems. Data from each stage of the shift register is latched on the negative transition of the strobe input. Data propagates through the latch while strobe is high. Outputs of the eight data latches are controlled by three-state buffers which are placed in the high-impedance state by a logic Low on Output Enable.

简介

MC14094B属于集成电路（IC）的移位寄存器。由制造生产的MC14094B移位寄存器移位寄存器是低级逻辑器件，通常用于在串行和并行方式之间转换数字逻辑信号形式的数据，或在数字字内移动数据位的位置。移位寄存器通常使用集成到一个设备中的一组触发器来实现，常用于集成度更高的逻辑器件，但仍可用于 I/O 扩展等应用，在这些应用中离散形式的函数可能会非常有用。
