HEF4794BT-Q100J 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 power supply range of 3 V to 15 V referenced to V (usually ground). Unused inputs must be connected to V, V, 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.
