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.

簡介

HCF4094屬于集成電路（IC）的移位寄存器。由制造生產的HCF4094移位寄存器移位寄存器是低級邏輯器件，通常用于在串行和并行方式之間轉換數(shù)字邏輯信號形式的數(shù)據，或在數(shù)字字內移動數(shù)據位的位置。移位寄存器通常使用集成到一個設備中的一組觸發(fā)器來實現(xiàn)，常用于集成度更高的邏輯器件，但仍可用于 I/O 擴展等應用，在這些應用中離散形式的函數(shù)可能會非常有用。
