DESCRIPTION
The HCF4094B is a monolithic integrated circuit
fabricated in Metal Oxide Semiconductor
technology available in DIP and SOP packages.
The HCF4094B is an 8 stages serial shift register
having a storage latch associated with each stage
for strobing data from the serial input to parallel
buffered 3-state outputs. The parallel outputs may
be connected directly to common bus lines. Data
is shifted on positive clock transition. The data in
each shift register stage is transferred to the
storage register when the STROBE input is high.
Data in the storage register appears atthe outputs
whenever the OUTPUT-ENABLE signal is high.
Two serial outputs are available for cascading a
number of HCF4094B devices. Data is available
at the QSserial output terminal on positive clock
edges to allow for high speed operation in
cascaded system in which the clock rise time is
fast. The same serial information, available at the
Q’Sterminal on the next negative clock edge,
provides a means for cascading HCF4094B
devices when the clock rise time is slow.
