MC14094屬于集成電路（IC）的移位寄存器。由安森美半導體公司制造生產(chǎn)的MC14094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(zhuǎn)換數(shù)字邏輯信號形式的數(shù)據(jù)，或在數(shù)字字內(nèi)移動數(shù)據(jù)位的位置。移位寄存器通常使用集成到一個設(shè)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(yīng)用，在這些應(yīng)用中離散形式的函數(shù)可能會非常有用。

The MC14094B combines an 8?stage shift register with a data latch for each stage and a 3?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 QSoutput data is for use in high?speed cascaded systems. The QSoutput 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 3?state buffers which are placed in the high?impedance state by a logic Low on Output Enable.
