Description
The STP16CPC05 is a monolithic, low voltage,
low current power 16-bit shift register designed for
LED panel displays. The STP16CPC05 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 STP16CPC05`s output stage is designed to
optimize the turn-on and turn-off time, typically
100 nS. The balanced turning ON/OFF improves
the system performances reducing the bypass
capacitance in applications where parasitic
inductance generate ringing or noise in the
system. The LEDs' brightness can be controlled
by using an external resistor to adjust the
STP16CPC05 output current.

The STP16CPC05 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
microcontroller.
