Description
The STP16CP596 is a monolithic, low voltage,
low current power 16-bit shift register designed for
LED panel displays. The STP16CP596 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
were designed to provide 3-50mA constant
current to drive the LEDs.
Compared with the STPIC6C595, the device
provides great flexibility and improved
performance in LED panel system design.

Users can adjust the STP16CP596 output current
with an external resistor, controlling the LEDs'
light intensity.
The STP16CP596 guarantees a 16V output
driving capability, allowing users to connect more
LEDs in series. The high clock frequency (25MHz)
also satisfies the high volume data transmission
system requirement. The 3.3V voltage supply is
useful for applications that interface any
microprocessor from 3.3V.
Compared with a standard TSSOP package, the
TSSOP exposed pad increases heat dissipation
capability by a factor of 2:5.
