DESCRIPTION

Trough an external resistor, users may adjust the

STP8CL596 output current, controlling in this way

the light intensity of LEDs.

The STP8CL596 is a monolithic, medium-voltage,

low current power 8-bit shift register designed for

LED panel display.

The STP8CL596 guarantees 16V output driving

capability, allowing users to connect more LEDs in

series. The high clock frequency, 25 MHz, also

satisfies the system requirement of high volume

data transmission. The 3.3V of voltage supply is

well useful for applications that interface any micro

from 3.3V to 5.5V. Compared with a standard

TSSOP package, the TSSOP exposed pad

increases heat dissipation capability by a 2.5

factor.

The STP8CL596 contains

a 8-bit serial-in,

parallel-out shift register that feeds a 8-bitD-type

storage register. In the output stage, sixteen

regulated current sources were designed to

provide 15-90mA constant current to drive the

LEDs.

Compared with the STPIC6C595, the device

provides

great

flexibility

and

improved

performance in LED panel system design.
