6 / 25 page TLC59283 SBVS199A – JUNE 2012 – REVISED JUNE 2012 www.ti.com PIN DESCRIPTIONS PIN NUMBER NAME DBQ RGE I/O DESCRIPTION All outputs empty (blank); Schmitt buffer input. When BLANK is high, all constant-current outputs (OUT0 to OUT15) are forced off and all pre-charge FETs are turned on. When BLANK is low, all BLANK 21 18 I constant-current outputs are controlled by the data in the output on or off data latch and all pre- charge FETs are turned off. This pin is internally pulled up to VCC with a 500-kΩ (typ) resistor. GND 1 22 — Power ground Constant-current value setting, the OUT0 to OUT15 sink constant-current outputs are set to the IREF 23 20 I/O desired values by connecting an external resistor between IREF and GND. Level-triggered latch; Schmitt buffer input. The data in the 16-bit shift register continue to transfer to the output on or off data latch while LAT is high. Therefore, if the data in the 16-bit shift register LAT 4 1 I are changed when LAT is high, the data in the data latch are also changed. The data in the data latch are held when LAT is low. This pin is internally pulled down to GND with a 500-k Ω (typ) resistor. Constant-current output. Each output can be tied together with others to increase the constant- OUT0 5 2 O current. Different voltages can be applied to each output. OUT1 6 3 O Constant-current output OUT2 7 4 O Constant-current output OUT3 8 5 O Constant-current output OUT4 9 6 O Constant-current output OUT5 10 7 O Constant-current output OUT6 11 8 O Constant-current output OUT7 12 9 O Constant-current output OUT8 13 10 O Constant-current output OUT9 14 11 O Constant-current output OUT10 15 12 O Constant-current output OUT11 16 13 O Constant-current output OUT12 17 14 O Constant-current output OUT13 18 15 O Constant-current output OUT14 19 16 O Constant-current output OUT15 20 17 O Constant-current output Serial data shift clock; Schmitt buffer input. SCLK 3 24 I All data in the 16-bit shift register are shifted toward the MSB by a 1-bit SCLK synchronization. Serial data input for driver on or off control; Schmitt buffer input. When SIN is high, the LSB is set to '1' for only one SCLK input rising edge. If two SCLK rising SIN 2 23 I edges are input while SIN is high, then the 16-bit shift register LSB and LSB+1 are set to '1'. When SIN is low, the LSB is set to '0' at the SCLK input rising edge. Serial data output. This output is connected to the 16-bit shift register MSB. SOUT data changes SOUT 22 19 O at the SCLK rising edge.
