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.
