The HCF4094 is a monolithic integrated circuit
fabricated in metal oxide semiconductor
technology available in PDIP-16 and SO-16
packages. The HCF4094 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. The parallel
outputs may be connected directly to common
bus lines. Data are shifted on positive clock
transition. The data in each shift register stage are
transferred to the storage register when the
STROBE input is high. Data in the storage
register appear at the outputs whenever the
OUTPUT-ENABLE signal is high. Two serial
outputs are available for cascading a number of
HCF4094 devices. Data are available at the QS
serial output terminal on positive clock edges to
allow for high speed operation in a cascaded
system in which the clock rise time is fast. The
same serial information, available at the Q’S
terminal on the next negative clock edge,
provides a means for cascading HCF4094
devices when the clock rise time is slow.
