Description
The HCF4094 is a monolithic integrated circuit fabricated in metal oxide semiconductor technology available in an SO-16 package. 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 Q
S
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.
