SBVS129 – MAY 2009 TERMINAL FUNCTIONS TERMINAL NO. NAME DAP RHB(1) I/O DESCRIPTION SIN 2 22 I Serial data input for the 25-bit common shift register Serial data shift clock. Data present on SIN are shifted to the LSB of the common shift register with the rising edge of SCLK. Data in the shift register are shifted SCLK 3 23 I toward the MSB at each rising edge of SCLK. The MSB data of the common shift register appear on SOUT. Edge triggered latch. The rising edge of LAT latches the data from the common LAT 4 24 I shift register into the output on/off data latch. See the Output On/Off Data Latch section for more details. All outputs are blank. When BLANK is high, all constant-current outputs (OUTR0-OUTR7, OUTG0-OUTG7, and OUTB0-OUTB7) are forced off. When BLANK 29 17 I BLANK is low, all constant current outputs are controlled by the on/off control data in the data latch. Reference current terminal. The maximum current for the outputs OUTR0-OUTR7, IREF 32 20 I/O OUTG0-OUTG7, and OUTB0-OUTB7 is set with a resistor from IREF to GND. Serial data output. The MSB of the 25-bit common shift register is shifted out at the SOUT 30 18 O rising edge of SCLK. Constant-current outputs for the RED LED group. 5, 8, 11, 14, 2, 5, 8, 11, Multiple outputs can be configured in parallel to increase the constant-current OUTR0- 17, 20, 23, 14, 25, 28, O capability. Different voltages can be applied to each output. These outputs are OUTR7 26 31 turned on/off by the BLANK signal and the data in the output on/off control data latch. Constant-current outputs for the GREEN LED group. 6, 9, 12, 15, 3, 6, 9, 12, Multiple outputs can be configured in parallel to increase the constant-current OUTG0- 18, 21, 24, 15, 26, 29, O capability. Different voltages can be applied to each output. These outputs are OUTG7 27 32 turned on/off by the BLANK signal and the data in the output on/off control data latch. Constant-current outputs for the BLUE LED group. 7, 10, 13, 1, 4, 7, 10, Multiple outputs can be configured in parallel to increase the constant-current OUTB0- 16, 19, 22, 13, 16, 27, O capability. Different voltages can be applied to each output. These outputs are OUTB7 25, 28 30 turned on/off by the BLANK signal and the data in the output on/off control data latch.
