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
DD
power 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. It is
also suitable for use over both the industrial (
40
°
C to +85
°
C) and automotive (
40
°
C to
+125
°
C) temperature ranges.
