STMICROELECTRONICS STP16CP05TTR Led Driver, 16 Outputs, Constant Current, 3V-5.5V in, 30MHz switch, 20V/100mA out, TSSOP-24 Leica 14354 The PCBs are clamped withoutThe STP16CP05TTR is a 16 bit Shift Register designed for LED panel displays. The STP16CP05 monolithic low voltage, low current power device 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 to 100mA constant current to drive the LEDs. The output current setup time is 40ns (typical), thus improving the system performance. The LED's
