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 VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input. 2. Features and benefits Fully static operation 5 V, 10 V, and 15 V parametric ratings Standardized symmetrical output characteristics Specified from 40 C to +85 C and 40 C to +125 C Complies with JEDEC standard JESD 13-B 3.
