TLC1549IDR from Texas Instruments, in a SOIC-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 | REF+ | input | The upper reference voltage value (nominally VCC) is applied to REF+. |
| 2 | ANALOG IN | input | Analog signal input with driving source impedance ≤ 1 kΩ and driving source current capability ≥ 10 mA. |
| 3 | REF- | input | The lower reference voltage value (nominally ground) is applied to REF-. |
| 4 | GND | power_in | The ground return for internal circuitry. |
| 5 | CS | input | Chip select; a high-to-low transition resets the internal counters and enables DATA OUT and I/O CLOCK. |
| 6 | DATA OUT | tri_state | 3-state serial output for the A/D conversion result; high-impedance state when CS is high and active when CS is low. |
| 7 | I/O CLOCK | input | Serial I/O clock input; on the third falling edge analog input sampling begins and continues until the tenth falling edge. |
| 8 | VCC | power_in | Positive supply voltage. |
