Description
General part information
STAP08DP05 Series
The STAP08DP05 is a monolithic, low voltage, low current power 8-bit shift register designed for LED panel displays. The STAP08DP05 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 are designed to provide 5-100 mA constant current to drive the LEDs.
The detection circuit checks 3 different conditions that can occur on the output line: short to GND, short to VOor open line. The data detection results are loaded in the shift register and shifted out via the serial line output.
STAP08DP05 detection functionality is implemented without increasing the pin number. Through a secondary function of the output enable and latch pin (DM1 and DM2 respectively), a dedicated logic sequence allows the device to enter or leave detection mode. Through an external resistor, users can adjust the output current of the STAP08DP05, thus controlling the light intensity of the LEDs. In addition, the user can adjust the intensity of the brightness of the LEDs from 0% to 100% through theOE/DM2pin.
