2 Description

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.
