74LV4094DB

8-stage shift-and-store bus register

The 74LV4094 is a low voltage Si-gate CMOS device and is pin and functional compatible with 74HC4094; 74HCT4094.

The 74LV4094 is an 8-stage serial shift register. It has a storage latch associated with each stage for strobing data from the serial input to parallel buffered 3-state outputs QP0 to QP7. The parallel outputs may be connected directly to common bus lines. Data is shifted on positive-going clock transitions. The data in each shift register stage is transferred to the storage register when the strobe (STR) input is HIGH. Data in the storage register appears at the outputs whenever the output enable (OE) signal is HIGH.

Two serial outputs (QS1 and QS2) are available for cascading a number of 74LV4094 devices. Serial data is available at QS1 on positive-going clock edges to allow high-speed operation in cascaded systems with a fast clock rise time. The same serial data is available at QS2 on the next negative going clock edge. This is used for cascading 74LV4094 devices when the clock has a slow rise time.

Not recommended for new designs (NRND).
