STP08CP05 Low voltage, low current power 8-bit shift register Features ■ ■ ■ ■ ■ ■ ■ ■ ■ Low voltage power supply down to 3 V 8 constant current output channels Adjustable output current through external resistor Serial Data IN/Parallel data OUT 3.3 V micro driver-able Output current: 5-100 mA 30MHz clock frequency Available in high thermal efficiency TSSOP exposed pad ESD protection 2.5 kV HBM, 200 V MM TSSOP16 SO-16 Dip-16 TSSOP16 (Exposed pad) Description The STP08CP05 is a monolithic, low voltage, low current, power 8-bit shift register designed for LED panel displays. The STP08CP05 contains an 8-bit serial-in, parallel-out shift register that feeds a 8-bit D-type storage register. In the output stage, eight regulated current sources were designed to provide 5-100 mA constant current to drive the LEDs, the output current setup time is 11 ns (typ), thus improving the system performance. The STP08CP05 is backward compatible in functionality and footprint with STP8C/L596. Through an external resistor, users can adjust the STP08CP05 output current, controlling in this way the light intensity of LEDs, in addition, user can adjust LED’s brightness intensity from 0% to 100% via OE pin. The STP08CP05 guarantees a 20 V output driving capability, allowing users to connect more LEDs in series. The high clock frequency, 30 MHz, also satisfies the system requirement of high volume data transmission. The 3.3 V of voltage supply is useful for applications that interface with any micro……
