MC14094BD

8级移位/存储寄存器具有三态输出 8-Stage Shift/Store Register with Three-State Outputs

The MC14094B combines an 8–stage shift register with a data latch for each stage and a three–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 Q′Soutput 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 three–state buffers which are placed in the high impedance state by a logic Low on Output Enable.
