Description
The STP16CPS05 is a monolithic, low voltage,
low current power 16-bit shift register designed for
LED panel displays. The STP16CPS05 contains a
16-bit serial-in, parallel-out shift register that
feeds a 16-bit, D-type storage register. In the
output stage, sixteen regulated current sources
provide from 5mA to 80mA constant current to
drive the LEDs.
The Auto Power Shut-Down and Auto Power-ON
feature allows the device to save power without
any external intervention.
Order codes
The output current setup time is 40ns (typ), thus
improving the system performance.
The LEDs' brightness can be controlled by using
an external resistor to adjust the STP16CPS05
output current.
The STP16CPS05 guarantees a 20V output
driving capability, allowing users to connect more
LEDs in series.The high clock frequency, 30MHz,
makes the device suitable for high data rate
transmission. The 3.3V voltage supply is useful in
applications that interface with a 3.3V
microntroller.

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. Refer also to the STMicroelectronics SURE
Program and other relevant quality documents.
