TLC59291RGER

Texas Instruments · LED Drivers · VQFN-24-EP(4x4)

TLC59291RGER from Texas Instruments, in a VQFN-24-EP(4x4). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 LAT input Data latch pin; rising edge latches 16-bit shift register data into output on/off data latch.
2 OUT0 output Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V.
3 OUT1 output Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V.
4 OUT2 output Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V.
5 OUT3 output Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V.
6 OUT4 output Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V.
7 OUT5 output Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V.
8 OUT6 output Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V.
9 OUT7 output Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V.
10 OUT8 output Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V.
11 OUT9 output Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V.
12 OUT10 output Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V.
13 OUT11 output Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V.
14 OUT12 output Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V.
15 OUT13 output Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V.
16 OUT14 output Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V.
17 OUT15 output Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V.
18 BLANK input Configurable blank/output enable pin; operates as SOUT select or output enable depending on FC9(BLANK Mode) bit; forces all OUTx off when high in enable mode.
19 SOUT output Serial data output from 16-bit shift register; data clocked out at SCLK rising edge; bit 7 or bit 15 selected by BLANK pin.
20 IREF input Current reference input; external resistor (1.32 kΩ to 66 kΩ) connected between IREF and GND sets maximum output current; direct GND connection forces all outputs off.
21 VCC power_in Power supply input; operating voltage range 3V to 5.5V.
22 GND power_in Ground reference.
23 SIN input Serial data input for 16-bit shift register; '1' written to LSB on SCLK rising edge when SIN is high.
24 SCLK input Serial clock input; data shifted at rising edge; maximum frequency 33 MHz.
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
