Description
The STP08CP05 is a monolithic, low voltage, low
current, power 8-bit shift register designed for
LED panel displays. The STP08CP05 contains a
8-bit serial-in, parallel-out shift register that feeds
a
8-bit D-type storage register. In the output stage,
eight regulated current sources were designed to
provide 5-100mA constant current to drive the
LEDs, the output current setup time is 10ns (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鈥檚 brightness intensity from 0% to
100% via
OE
pin.
The STP08CP05 guarantees a 20V 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 3.3V of voltage supply is
useful for applications that interface with any
micro from 3.3V. Compared with a standard
TSSOP package, the TSSOP exposed pad
increases heat dissipation capability by a 2.5
factor.
