HCC4094B

The HCC/HCF4094B are monolithic integrated circuits available in 16-lead dual in-line plastic or ceramic packageand plastic micropackage.

The HCC/HCF4094B 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 is shifted on positive clock transitions. The data in each shift register stage is transferred to the storage register when the STROBE input is high. Data in thestorage register appears at the outputs whenever the OUTPUT-ENABLE signal is high. Two serial outputs are available for cascading a number of HCC/HCF4094B devices. Data is available at the QS serial output terminal on positive clock edges to allow for high-speed operation in cascaded systems in which the clock rise time is fast. The same serial information, available at theQ'S terminal on the next negative clock edge, provides a means for cascading HCC/HCF4094B devices when the clock rise time is slow.
