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 QS output data is for use in
high–speed cascaded systems. The Q′S output 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.
