Description

The STP16CPP05 is a monolithic, low voltage,

low current power 16-bit shift register designed for

LED panel displays. The STP16CPP05 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 3 mA to 40 mA constant current to

drive the LEDs.

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 STP16CPP05

output current.

The STP16CPP05 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.
