TLC1543IDWR 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 | A0 | input | Analog signal input (one of 11 channels); driving source impedance ≤1 kΩ. |
| 2 | A1 | input | Analog signal input (one of 11 channels); driving source impedance ≤1 kΩ. |
| 3 | A2 | input | Analog signal input (one of 11 channels); driving source impedance ≤1 kΩ. |
| 4 | A3 | input | Analog signal input (one of 11 channels); driving source impedance ≤1 kΩ. |
| 5 | A4 | input | Analog signal input (one of 11 channels); driving source impedance ≤1 kΩ. |
| 6 | A5 | input | Analog signal input (one of 11 channels); driving source impedance ≤1 kΩ. |
| 7 | A6 | input | Analog signal input (one of 11 channels); driving source impedance ≤1 kΩ. |
| 8 | A7 | input | Analog signal input (one of 11 channels); driving source impedance ≤1 kΩ. |
| 9 | A8 | input | Analog signal input (one of 11 channels); driving source impedance ≤1 kΩ. |
| 10 | GND | power_in | Ground return terminal for internal circuitry; reference point for all voltage measurements. |
| 11 | A9 | input | Analog signal input (one of 11 channels); driving source impedance ≤1 kΩ. |
| 12 | A10 | input | Analog signal input (one of 11 channels); driving source impedance ≤1 kΩ. |
| 13 | REF- | input | Lower reference voltage input (nominally ground); sets lower end of conversion range. |
| 14 | REF+ | input | Upper reference voltage input (nominally VCC); maximum input voltage range determined by difference between REF+ and REF- terminals. |
| 15 | CS | input | Chip select input; high-to-low transition resets internal counters and enables device; low-to-high transition disables device. |
| 16 | DATA OUT | tri_state | 3-state serial output for A/D conversion result; high-impedance when CS is high, active when CS is low; outputs MSB-first on I/O CLOCK falling edges. |
| 17 | ADDRESS | input | 4-bit serial address input; selects desired analog channel or test voltage; MSB-first, shifts in on first four rising edges of I/O CLOCK. |
| 18 | I/O CLOCK | input | Serial clock input; controls address loading on rising edges, sampling timing, and data output shifting on falling edges. |
| 19 | EOC | output | End-of-conversion output; goes low on tenth I/O CLOCK trailing edge and returns high when conversion is complete. |
| 20 | VCC | power_in | Positive supply voltage input. |
