HCF4094中文资料8级移位和存储总线寄存器数据手册ST规格书

描述 Description

The HCF4094 is a monolithic integrated circuit fabricated in metal oxide semiconductor technology available in an SO-16 package. The HCF4094 is an 8-stage, serial shift register having a storage latch associated with each stage for strobing data from the serial input to parallel buffered 3-state outputs. The parallel outputs may be connected directly to common bus lines. Data are shifted on positive clock transition. The data in each shift register stage are transferred to the storage register when the STROBE input is high. Data in the storage register appear at the outputs whenever the OUTPUT-ENABLE signal is high. Two serial outputs are available for cascading a number of HCF4094 devices. Data are available at the QSserial output terminal on positive clock edges to allow for high speed operation in a cascaded system in which the clock rise time is fast. The same serial information, available at the Q’Sterminal on the next negative clock edge, provides a means for cascading HCF4094 devices when the clock rise time is slow.

简介

HCF4094属于集成电路（IC）的移位寄存器。由制造生产的HCF4094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。
