Description

The STP16CPS05 is a monolithic, low voltage,

low current power 16-bit shift register designed for

LED panel displays. The STP16CPS05 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

provide from 5mA to 80mA constant current to

drive the LEDs.

The Auto Power Shut-Down and Auto Power-ON

feature allows the device to save power without

any external intervention.

The output current setup time is 40ns (typ), thus

improving the system performance.

The LEDs' brightness can be controlled by using

an external resistor to adjust the STP16CPS05

output current.

The STP16CPS05 guarantees a 20V output

driving capability, allowing users to connect more

LEDs in series.The high clock frequency, 30MHz,

makes the device suitable for high data rate

transmission. The 3.3V voltage supply is useful in

applications that interface with a 3.3V

microntroller.
