HCF4094 8-Stage Shift-AND-Store Bus Register

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 at the 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 QS serial 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'S terminal on the next negative clock edge, provides a means for cascading HCF4094B devices when the clock rise time is slow
