8-stage shift-and-store register LED driver

HEF4794B

APPLICATIONS

• Automotive

• Industrial.

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.
