Datasheet - production data
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 OE 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.
