CD4031B中文资料CMOS 64 级静态移位寄存器数据手册TI规格书

描述 Description

CD4031B is a static shift register that contains 64 D-type, master-slave flip-flop stages and one stage which is a D-type master flip-flop only (referred to as a 1/2 stage).
The logic level present at the DATA input is transferred into the first stage and shifted one stage at each positive-going clock transition.Maximum clock frequencies up to 12 Megahertz (typical) can be obtained.Because fully static operation is allowed, information can be permanently stored with the clock line in either the low or high state.The CD4031B has a MODE CONTROL input that, when in the high state, allows operation in the recirculating mode.The MODE CONTROL input can also be used to select between two separate data sources.Register packages can be cascaded and the clock lines driven directly for high-speed operation.Alternatively, a delayed clock output (CLD) is provided that enables cascading register packages while allowing reduced clock drive fan-out and transition-time requirements.A third cascading option makes use of the Q' output from the 1/2 stage, which is available on the next negative-going transition of the clock after the Q output occurs.This delayed output, like the delayed clock CLD, is used with clocks having slow rise and fall times.
The CD4031B types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (NSR suffix), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).

简介

CD4031B属于集成电路（IC）的移位寄存器。由TI制造生产的CD4031B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。
