Description
The STP16DP05 is a monolithic, low voltage, low
current power 16-bit shift register designed for
LED panel displays. The device contains a 16-bit
SO-24
QSOP-24
serial-in, parallel-out shift register that feeds a 16-
bit D-type storage register. In the output stage,
sixteen regulated current sources were designed
to provide 5-100 mA constant current to drive the
LEDs. The STP16DP05 features open and short

Electrical ratings
Absolute maximum ratings
Stressing the device above the rating listed in the “absolute maximum ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the operating sections of
this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
