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.
