Description
The STP16CP05 is a monolithic, low voltage, low
current power 16-bit shift register designed for
LED panel displays. The STP16CP05 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 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 STP16CP05
output current.

The STP16CP05 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.
