CD74HC4094M96G4集成电路（IC）的移位寄存器规格书PDF中文资料

CD74HC4094M96G4属于集成电路（IC）的移位寄存器。由德州仪器制造生产的CD74HC4094M96G4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。

2 Description

The CDx4HC4094 and CD74HCT4094 are 8-stage

serial shift registers having a storage latch associated

with each stage for strobing data from the serial

input to parallel buffered tri-state outputs. The parallel

outputs may be connected directly to common bus

lines. Data is shifted on positive clock transitions. The

data in each shift register stage is transferred to the

storage register when the Strobe input is high. Data in

the storage register appears at the outputs whenever

the Output-Enable signal is high.
