TPIC6595DWR from Texas Instruments, in a SOIC-20-300mil. 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 | PGND | power_in | Power ground; pins 1, 10, 11, and 20 must all be externally connected to system ground to minimize parasitic inductance. |
| 2 | VCC | power_in | Power supply input, recommended operating range 4.5V to 5.5V. |
| 3 | SER IN | input | Serial data input to shift register with 10ns setup and hold time requirements. |
| 4 | DRAIN0 | tri_state | Open-drain output with 45V rating, 250mA continuous sink current, and 1.5A pulsed current capability. |
| 5 | DRAIN1 | tri_state | Open-drain output with 45V rating, 250mA continuous sink current, and 1.5A pulsed current capability. |
| 6 | DRAIN2 | tri_state | Open-drain output with 45V rating, 250mA continuous sink current, and 1.5A pulsed current capability. |
| 7 | DRAIN3 | tri_state | Open-drain output with 45V rating, 250mA continuous sink current, and 1.5A pulsed current capability. |
| 8 | SRCLR | input | Shift register clear input, active-low; clears all internal registers when pulled low. |
| 9 | G | input | Output enable input, active-low; when high, all outputs are off; when low, data is transparent to output buffers. |
| 10 | PGND | power_in | Power ground; pins 1, 10, 11, and 20 must all be externally connected to system ground to minimize parasitic inductance. |
| 11 | PGND | power_in | Power ground; pins 1, 10, 11, and 20 must all be externally connected to system ground to minimize parasitic inductance. |
| 12 | RCK | input | Register clock input; transfers data from shift register to storage register on rising edge when RCK is low for write/read validity. |
| 13 | SRCK | input | Shift register clock input; shifts data on rising edge with 10ns setup and hold time requirements. |
| 14 | DRAIN4 | tri_state | Open-drain output with 45V rating, 250mA continuous sink current, and 1.5A pulsed current capability. |
| 15 | DRAIN5 | tri_state | Open-drain output with 45V rating, 250mA continuous sink current, and 1.5A pulsed current capability. |
| 16 | DRAIN6 | tri_state | Open-drain output with 45V rating, 250mA continuous sink current, and 1.5A pulsed current capability. |
| 17 | DRAIN7 | tri_state | Open-drain output with 45V rating, 250mA continuous sink current, and 1.5A pulsed current capability. |
| 18 | SER OUT | output | Serial data output from shift register for cascading data to additional devices in daisy-chain configuration. |
| 19 | LGND | power_in | Logic ground with single-point external connection required to PGND to reduce crosstalk between logic and load circuits. |
| 20 | PGND | power_in | Power ground; pins 1, 10, 11, and 20 must all be externally connected to system ground to minimize parasitic inductance. |
