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.
