8-stage shift-and-store register LED driver

Rev. 1 — 7 August 2012

Product data sheet

1. General description

The HEF4794B-Q100 is an 8-stage serial shift register. It has a storage latch associated

with each stage for strobing data from the serial input (D) to the parallel LED driver outputs

(QP0 to QP7). Data is shifted on the positive-going clock (CP) transitions. The data in

each shift register stage is transferred to the storage register when the strobe input (STR)

is HIGH. Data in the storage register appears at the outputs whenever the output enable

input (OE) signal is HIGH.

Two serial outputs (QS1 and QS2) are available for cascading a number of

HEF4794B-Q100 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 HEF4794B-Q100 devices when the clock has a slow rise time.

It operates over a recommended V_DDpower supply range of 3 V to 15 V referenced to V_SS

(usually ground). Connect unused inputs to V_DD, V_SS, or another input.

This product has been qualified to the Automotive Electronics Council (AEC) standard

Q100 (Grade 1) and is suitable for use in automotive applications.
