Description
for cascading these devices when the clock rise time is slow.
The Harris CD74HC4094 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 three-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.
Ordering Information
PART NUMBER
Two serial outputs are available for cascading a number of
these devices. Data is available at the QS1 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 QS2
terminal on the next negative clock edge, provides a means
