Internal 5 V shunt regulator allows operation from 6-24 V via a series resistor (e.g. 50 Ω @ 6 V, 1.8 kΩ @ 24 V) with ~10 mA into VDD. |+| 2 | DO | output | Single-wire cascade data output. Reshapes and forwards downstream data to the next TM1926D's DIN after the local 96-bit (24x4) frame is captured. VOH >= VDD-0.5 V @ -6 mA, VOL <= 0.4 V @ 10 mA. |+| 3 | OUTR4 | output | Red channel constant-current sink for pixel 4. 17 mA typ (16-18 mA), OUT rated to 24 V, 8-bit PWM at ~3.8 kHz. Open-drain sink to LED cathode; anode returned to VLED. |+| 4 | OUTG4 | output | Green channel constant-current sink for pixel 4. 17 mA typ, 8-bit PWM brightness, OUT withstand 24 V. |+| 5 | OUTB4 | output | Blue channel constant-current sink for pixel 4. 17 mA typ, 8-bit PWM brightness, OUT withstand 24 V. |+| 6 | OUTR3 | output | Red channel constant-current sink for pixel 3. 17 mA typ, 8-bit PWM brightness, OUT withstand 24 V. |+| 7 | OUTG3 | output | Green channel constant-current sink for pixel 3. 17 mA typ, 8-bit PWM brightness, OUT withstand 24 V. |+| 8 | OUTB3 | output | Blue channel constant-current sink for pixel 3. 17 mA typ, 8-bit PWM brightness, OUT withstand 24 V. |+| 9 | GND | power_in | System ground reference for logic and constant-current sinks. |+| 10 | OUTB2 | output | Blue channel constant-current sink for pixel 2. 17 mA typ, 8-bit PWM brightness, OUT withstand 24 V. |+| 11 | OUTG2 | output | Green channel constant-current sink for pixel 2. 17 mA typ, 8-bit PWM brightness, OUT withstand 24 V. |+| 12 | OUTR2 | output | Red channel constant-current sink for pixel 2. 17 mA typ, 8-bit PWM brightness, OUT withstand 24 V. |+| 13 | OUTB1 | output | Blue channel constant-current sink for pixel 1. 17 mA typ, 8-bit PWM brightness, OUT withstand 24 V. |+| 14 | OUTG1 | output | Green channel constant-current sink for pixel 1. 17 mA typ, 8-bit PWM brightness, OUT withstand 24 V. |+| 15 | OUTR1 | output | Red channel constant-current sink for pixel 1. 17 mA typ, 8-bit PWM brightness, OUT withstand 24 V. |+| 16 | DIN | input | Single-wire cascade data input. Return-to-zero encoded, ~800 kHz bit rate, T0H/T1H distinguish 0/1. VIH >= 3.5 V @ VDD=5 V, VIL <= 1.35 V.
