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-bit, D-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 falling

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, 25MHz, 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.
