Description
The STP16CP05 is a monolithic, low voltage, low current power 16-bit shift register designed for LED panel displays. The STP16CP05 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 5 mA to 100 mA constant current to drive the LEDs. The output current setup time is 40 ns (typ), thus improving the system performance. The LEDs' brightness can be controlled by using an external resistor to adjust the STP16CP05 output current. The STP16CP05 guarantees a 20 V output driving capability, allowing users to connect more LEDs in series.The high clock frequency, 30 MHz, makes the device suitable for high data rate transmission. The 3.3 V voltage supply is useful in applications that interface with a 3.3 V micro controller.

The latches circuit holds data when the LE terminal is Low. When LE terminal is at high level, latch circuit does not hold the data it passes from the input to the output. When OE terminal is at low level, output terminals OUT0 to OUT15 respond to the data, either ON or OFF. When OE terminal is at high level, it switches off all the data on the output terminal.
