Description

The STP08CP05 is a monolithic, low voltage, low

current, power 8-bit shift register designed for

LED panel displays. The STP08CP05 contains an

8-bit serial-in, parallel-out shift register that feeds

an 8-bit D-type storage register. In the output

stage, eight regulated current sources were

designed to provide 5-100 mA constant current to

drive the LEDs, the output current setup time is 11

ns (typ), thus improving the system performance.

The STP08CP05 is backward compatible in

functionality and footprint with STP8C/L596.

Through an external resistor, users can adjust the

STP08CP05 output current, controlling in this way

the light intensity of LEDs, in addition, user can

adjust LED’s brightness intensity from 0% to

100% via

pin.

The STP08CP05 guarantees a 20 V output

driving capability, allowing users to connect more

LEDs in series. The high clock frequency, 30

MHz, also satisfies the system requirement of

high volume data transmission. The 3.3 V of

voltage supply is useful for applications that

interface with any micro from 3.3 V. Compared

with a standard TSSOP package, the TSSOP

exposed pad increases heat dissipation capability

by a 2.5 factor.
