DESCRIPTION
The STP16C596 is a monolithic, medium-voltage,
low current power 16-bit shift register designed for
LED panel displays. The STP16C596 contains a
16-bit serial-in, parallel-out shift register that feeds
a 16-bitD-type storage register. In the output
stage, sixteen regulated current sources are
designed to provide 15-120mA constant current to
drive the LEDs.
The serial output change state on the failing edges
of clock, this special feature will provide an
improved performance of the application when the
clock signal is skewed because the daisy chain is
too long.

Through an external resistor, users may adjust the
STP16C596 output current, controlling in this way
the light intensity of LEDs.
The STP16C596 guarantees a 16V output driving
capability, allowing users to connect more LEDs in
series. The high clock frequency, 25 MHz, also
satisfies the system demand for high volume data
transmission. Compared with a standard TSSOP
package, the TSSOP exposed pad increases heat
dissipation capability by a 2.5 factor.
