DESCRIPTION
TSSOP16
The STP08C596 is a monolithic, medium-voltage,
low current power 8-bit shift register designed for
LED panel display. The STP08C596 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 15-120mA constant current to drive the
LEDs.
Trough an external resistor, users may adjust the
STP08C596 output current, controlling in this way
the light intensity of LEDs.
The STP08C596 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.
Compared with the STPIC6C595, the device
provides
great
flexibility
and
improved
performance in LED panel system design.
