TLC0820AIDWR from Texas Instruments, in a SOIC-20-300mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ANLG IN | input | Analog input accepts voltages from -0.1 V to VCC + 0.1 V for A/D conversion. |
| 2 | D0 | tri_state | 3-state output for digital data bit 1 (LSB). |
| 3 | D1 | tri_state | 3-state output for digital data bit 2. |
| 4 | D2 | tri_state | 3-state output for digital data bit 3. |
| 5 | D3 | tri_state | 3-state output for digital data bit 4. |
| 6 | WR/RDY | bidirectional | Write input in write-read mode or ready open-drain output in read mode; requires external pullup resistor. |
| 7 | MODE | input | Mode select input; low selects read mode, high selects write-read mode; internally pulled to GND with 50 µA current source. |
| 8 | RD | input | Read input; activates data outputs in write-read mode or initiates conversion in read mode when CS is low. |
| 9 | INT | output | Interrupt output goes low when conversion completes (typically 800 ns after WR rising edge) and is reset by CS or RD rising edge. |
| 10 | GND | power_in | Ground reference potential. |
| 11 | REF- | input | Negative reference voltage input placed on resistor ladder bottom; defines full-scale range with REF+; valid range GND to REF+. |
| 12 | REF+ | input | Positive reference voltage input placed on resistor ladder top; defines full-scale range with REF-; valid range REF- to VCC. |
| 13 | CS | input | Chip select input; must be low to enable RD or WR commands; resets INT on rising edge. |
| 14 | D4 | tri_state | 3-state output for digital data bit 5. |
| 15 | D5 | tri_state | 3-state output for digital data bit 6. |
| 16 | D6 | tri_state | 3-state output for digital data bit 7. |
| 17 | D7 | tri_state | 3-state output for digital data bit 8 (MSB). |
| 18 | OFLW | output | Overflow indicator output; normally high, goes low at end of conversion if analog input exceeds Vref+. |
| 19 | NC | unconnected | No internal connection. |
| 20 | VCC | power_in | Power supply voltage; recommended operating range 4.5 V to 8 V with decoupling capacitors. |
