High Speed CMOS Logic 8-Stage Shift-and-Store Bus Register with 3-Stage Outputs

The CDx4HC4094 and

CD74HCT4094 are 8-stage serial shift registers having a

storage latch associated with each stage for strobing data

from the serial input to parallel buffered tri-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 the storage register appears at the outputs

whenever the Output-Enable signal is high.
