HEF4894B 12-stage shift-and-store register LED driver Rev. 7 — 13 August 2010 Product data sheet 1. General description The HEF4894B is a 12-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 QP11). Data is shifted on positive-going clock (CP) 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 output whenever the output enable (OE) input signal is HIGH. Two serial outputs (QS1 and QS2) are available for cascading a number of HEF4894B 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 HEF4894B 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. It is also suitable for use over both the industrial (−40 °C to +85 °C) and automotive (−40 °C to +125 °C) temperature ranges. 2. Features and benefits Fully static operation 5 V, 10 V, and 15 V parametric ratings Standardized symmetrical output characteristics Operates across the automotive temperature range from −40 °C to +125 °C Complies with JEDEC standard JESD 13-B 3.
