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 5 mA to 100 mA constant current to
drive the LEDs.
The STP16CP05 guarantees a 20 V output
driving capability, allowing users to connect more
LEDs in series.The high clock frequency, 30 MHz,
makes the device suitable for high data rate
transmission. The 3.3 V voltage supply is useful in
applications that interface with a 3.3 V micro
controller.
The output current setup time is 40 ns (typ), thus
improving the system performance.
The LEDs' brightness can be controlled by using
an external resistor to adjust the STP16CP05
output current.
