MC14094B
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 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 Q
S
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 3−state buffers
which are placed in the high−impedance state by a logic Low on
Output Enable.

This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
high−impedance circuit. For proper operation, V

should be constrained
to the range V

Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either V
