TYPE DESCRIPTION
NAME DIP NO. PWP NO. RHB NO.
Blank all outputs. When BLANK = H, all OUTn outputs are forced OFF.
BLANK 23 2 31 I GS counter is also reset. When BLANK = L, OUTn are controlled by
grayscale PWM control.
Switch DC data input. When DCPRG = L, DC is connected to
EEPROM. When DCPRG = H, DC is connected to the DC register.
DCPRG 19 26 25 I
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

Multifunction input pin. When VPRG = GND, the device is in GS mode.
When VPRG = V

,
VPRG 27 6 3 I
DC register data can programmed into DC EEPROM with
DCPRG=HIGH. EEPROM data = 3 Fh (default)
Error output. XERR is an open-drain terminal. XERR goes L when LOD
XERR 16 23 22 O
or TEF is detected.
Level triggered latch signal. When XLAT = high, the TLC5940 writes
data from the input shift register to either GS register (VPRG = low) or
XLAT 24 3 32 I
DC register (VPRG = high). When XLAT = low, the data in GS or DC
register is held constant.
