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