XD331 from XINLUDA, in a DIP-8. 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 | IOUT | output | Current output from switched current source; supplies charging current to external timing capacitor, nominally 136 µA for RS = 14 kΩ (XD331). |
| 2 | IREF | input | Reference current input; regulated at 1.9 VDC, connect external resistor RS to ground to establish reference current i = 1.9V/RS. |
| 3 | FOUT | tri_state | Frequency output; open-collector pulse train output proportional to input voltage, requires external pullup resistor to VCC. |
| 4 | GND | power_in | Ground; circuit reference point for all voltage measurements and return path. |
| 5 | RC | input | Timing network capacitor input; charged by current source until voltage reaches ⅔ VCC threshold, nominal 0.667 × VS. |
| 6 | THRESH | input | Threshold comparator input; provides reference voltage for timer comparator or receives external input in F-to-V mode. |
| 7 | COMPIN | input | Comparator positive input; receives input signal voltage for voltage-to-frequency conversion. |
| 8 | VS | power_in | Supply voltage input; positive power supply rail, operating range 4 V to 40 V. |
