HEF4794B

8-stage shift-and-store register LED driver

Rev. 7 — 16 November 2011

Product data sheet

1. General description

The HEF4794B 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

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 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). Unused inputs must be connected to V_DD, V_SS, or another input.

2. Features and benefits

 Fully static operation
