HEF4894B
12-stage shift-and-store register LED driver
Rev. 10 — 23 November 2021
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.

Definitions
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those
given in the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
