TM512AB3 from TM Shenzhen Titan Micro Elec, in a SOP-8. 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 | PO | output | Address write-code line output used to cascade the address-programming signal to the next TM512AB3 in the chain; the electrical table gives a drive capability of 50 mA source at Vo = 4 V and 50 mA sink at Vo = 0.4 V. |
| 2 | OUTR | output | Constant-current PWM output channel (red) with a preset 18 mA sink current; the output withstand voltage is 26 V recommended and 30 V maximum. |
| 3 | OUTG | output | Constant-current PWM output channel (green) with a preset 18 mA sink current; the output withstand voltage is 26 V recommended and 30 V maximum. |
| 4 | OUTB | output | Constant-current PWM output channel (blue) with a preset 18 mA sink current; the output withstand voltage is 26 V recommended and 30 V maximum. |
| 5 | GND | power_in | Ground reference; all datasheet voltage values are specified relative to system ground. |
| 6 | DI | input | DMX512 data input that auto-adapts to 200 Kbps to 1000 Kbps; logic high must be at least 0.7VDD and logic low at most 0.3VDD. |
| 7 | PI | input | Address write-code line input with an internal pull-up; switching thresholds are 0.7VDD (high) and 0.3VDD (low) at VDD = 5 V. |
| 8 | VDD | power_in | Supply pin with an internal 5 V regulator (zener); recommended supply 3.8 V to 6 V (typical 5.3 V) and absolute limit 5.5 V to 6.5 V. |
