Pin Functions
| PIN | TYPE | DESCRIPTION | |||
|---|---|---|---|---|---|
| NAME | DIP NO. | PWP NO. | RHB NO. | ||
| BLANK | 23 | 2 | 31 | I | Blank all outputs. When BLANK = H, all OUTn outputs are forced OFF. GS counter is also reset. When BLANK = L, OUTn are controlled by grayscale PWM control. |
| DCPRG | 19 | 26 | 25 | I | Switch DC data input. When DCPRG = L, DC is connected to EEPROM. When DCPRG = H, DC is connected to the DC register. DCPRG also controls EEPROM writing, when VPRG = V(PRG). EEPROM data = 3 Fh (default) |
| GND | 22 | 1 | 30 | G | Ground |
| GSCLK | 18 | 25 | 24 | I | Reference clock for grayscale PWM control |
| IREF | 20 | 27 | 26 | I | Reference current terminal |
| NC | — | — | 12 | — | No connection |

| OUT0 | 28 | 7 | 4 | O | Constant current output |
| OUT1 | 1 | 8 | 5 | O | Constant current output |
| OUT2 | 2 | 9 | 6 | O | Constant current output |
| OUT3 | 3 | 10 | 7 | O | Constant current output |
| OUT4 | 4 | 11 | 8 | O | Constant current output |
| OUT5 | 5 | 12 | 9 | O | Constant current output |
| OUT6 | 6 | 13 | 10 | O | Constant current output |
| OUT7 | 7 | 14 | 11 | O | Constant current output |
| OUT8 | 8 | 15 | 14 | O | Constant current output |
| OUT9 | 9 | 16 | 15 | O | Constant current output |
| OUT10 | 10 | 17 | 16 | O | Constant current output |
| OUT11 | 11 | 18 | 17 | O | Constant current output |
| OUT12 | 12 | 19 | 18 | O | Constant current output |
| OUT13 | 13 | 20 | 19 | O | Constant current output |
| OUT14 | 14 | 21 | 20 | O | Constant current output |
| OUT15 | 15 | 22 | 21 | O | Constant current output |
| SCLK | 25 | 4 | 1 | I | Serial data shift clock |
| SIN | 26 | 5 | 2 | I | Serial data input |
| SOUT | 17 | 24 | 23 | O | Serial data output |
| VCC | 21 | 28 | 27 | I | Power supply voltage |
| VPRG | 27 | 6 | 3 | I | Multifunction input pin. When VPRG = GND, the device is in GS mode. When VPRG = VCC, the device is in DC mode. When VPRG = V(VPRG), DC register data can programmed into DC EEPROM with DCPRG=HIGH. EEPROM data = 3 Fh (default) |
| XERR | 16 | 23 | 22 | O | Error output. XERR is an open-drain terminal. XERR goes L when LOD or TEF is detected. |
| XLAT | 24 | 3 | 32 | I | Level triggered latch signal. When XLAT = high, the TLC5940 writes data from the input shift register to either GS register (VPRG = low) or DC register (VPRG = high). When XLAT = low, the data in GS or DC register is held constant. |
