General Description
HEF4794B General Description
The HEF4794B is an 8-stage serial shift register having a storage latch associated with each stage for strobing data from the serial input to parallel LED driver outputs O0 to O7. 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 (EO) signal is HIGH.
Two serial outputs (OS and OS') are available for cascading a number of HEF4794B devices. Data is available at OS on positive-going clock edges to allow high-speed operation in cascaded systems in which the clock rise time is fast. The same serial information is available at OS' on the next negative-going clock edge and provides cascading HEF4794B devices when the clock rise time is slow.
