DESCRIPTION
The STP8CL596 is a monolithic, medium-voltage,
low current power 8-bit shift register designed for
LED panel display.
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.
Trough an external resistor, users may adjust the
STP8CL596 output current, controlling in this way
the light intensity of LEDs.
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.
