MC14094B
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.

PIN ASSIGNMENT
This device contains protection circuitry to
guard against damage due to high static
voltages or electric fields. However, pre-
cautions must be taken to avoid applications of
any voltage higher than maximum rated volt-
ages to this high–impedance circuit. For proper
operation, Vin and Vout should be constrained
to the range VSS
(Vin or Vout)
Unused inputs must always be tied to an
appropriate logic voltage level (e.g., either VSS
or VDD). Unused outputs must be left open.
VDD.
