DESCRIPTION
The HEF4094B is an 8-stage serial shift register having a
storage latch associated with each stage for strobing data
from the serial input to parallel buffered 3-state outputs
O0 to O7. The parallel outputs may be connected directly
to common bus lines. Data is shifted on positive-going
clock transitions. The data in each shift register stage is
transferred to the storage register when the strobe (STR)
input is HIGH. Data in the storage register appears at the
outputs whenever the output enable (EO) signal is HIGH.
Two serial outputs (Os and O’s) are available for cascading
a number of HEF4094B devices. Data is available at Os on
positive-going clock edges to allow high-speed operation
in cascaded systems in which the clock rise time is fast.
The same serial information is available at O’s on the next
negative-going clock edge and provides cascading
HEF4094B devices when the clock rise time is slow.
