| PIN | I/O | DESCRIPTION | ||
|---|---|---|---|---|
| NAME | RRF NO. | ZXL NO. | ||
| IREF | 20 | J1 | I | Pin for setting the maximum constant-current value. Connecting an external resistor between IREF and GND sets the maximum current for each constant-current output channel. When this pin is connected directly to GND, all outputs are forced off. The external resistor should be placed close to the device. |
| VCC | 8 | F1 | I | Device power supply. |
| VR | 9, 10 | G1, H1 | I | Red LED power supply. |
| VG | 51, 50 | E11, F11 | I | Green LED power supply. |
| VB | 49, 48 | G11, H11 | I | Blue LED power supply. |
| R0-R15 | 1, 4, 11, 14, 17, 21, 24, 27, 32, 35, 38, 41, 44, 47, 54, 57 | B5, B2,F2, F4, J2, L1, K3, H5, L6, L7, L8, L10, K10, H10, E10, E8 | O | Red LED Constant-current output. |
| G0-G15 | 2, 5, 12, 15, 18, 22, 25, 28, 31, 34, 37, 40, 43, 46, 53, 56 | B4, C2, G2, G4, K1, L2, K4, K5, K6, K7, K8, L9, K11, J10, F10, F8 | O | Green LED Constant-current output. |
| B0-B15 | 3, 6, 13, 16, 19, 23, 26, 29, 30, 33, 36, 39, 42, 45, 52, 55 | B3, D2, H2, H4, K2, L3, L4, L5, H6, H7, H8, K9, L11, J11, G10, G8 | O | Blue LED Constant-current output. |
