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.
