HEF4794B - 8-stage shift-and-store register LED driver

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.

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.
