CD74HC4094PWR

The OHC4094 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. Two serial outputs are available for cascading a number of these devices. Data is available at the ΩS₁ 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 ΩS₂ terminal on the next negative clock edge, provides a means for cascading these devices when the clock rise time is slow.
