MC14094B数据手册集成电路（IC）的移位寄存器规格书PDF

描述 Description

TheMC14094B combines an 8–stage shift register with adata latch for each stage and a three–state output from each latch. Datais shifted on the positive clock transition and is shifted from the seventh stage to two serial outputs. The QSoutput data is forusein high–speed cascaded systems. The Q′Soutput data is shifted on the following negative clock transition for use in low–speed cascaded systems. Datafrom each stage of the shift register is latched on the negative transitionof the strobe input. Data propagates through the latch while strobe is high. Outputsof the eightdata latches are controlled by three–state buffers whichare placed inthe high–impedance state by a logic Low on Output Enable.
